Signal Blocking Mobile Phone Cases Development

EMF/RF shielded bags and pouches to protect against excessive exposure to electromagnetic radiation from devices like cellphones, tablets, and laptops. The bags have a conductive lining throughout or in certain compartments to block RF signals from penetrating. This allows users to carry their devices in the shielded compartments to reduce exposure compared to carrying them openly.

A protective case for smartphones and other handheld electronic devices that can be easily switched between open and closed positions to block or allow wireless signals. The case has movable panels that can be extended outwards to cover the device antennas and block wireless signals when privacy is desired. The panels can then be retracted back into the case to allow normal wireless signal transmission and reception. This provides a convenient way for users to quickly control the device's wireless connectivity to prevent unauthorized access to their data or tracking of their location.

Reversible collapsible security pouch for electronic devices that provides RF shielding to protect against electronic device hacking. The pouch can be compactly rolled and secured with a wrapping loop for portability but expands to accommodate devices like key fobs. It has a built-in Faraday cage to block RF signals. Some versions can also lock to prevent access when the device is not present.

A cell phone case design that redirects radiation away from the user while amplifying audio to reduce radiation exposure and improve sound quality. The case has a hinged front plate with slots for the camera and buttons and a back plate with a lip to hold the phone. A concave copper shield between the plates redirects radiation away from the body. The front plate has audio amplification slots matching copper shield openings.

This cellphone case redirects radiation away from the user, amplifies speaker audio, and shields radio signals. The case has a hinged front and back plate made of dense wood that insulates heat. The front plate has a slotted design to redirect radiation away from the body while matching audio openings to amplify sound. The back plate has a lip to hold the phone, allowing access to buttons and ports. A concave copper shield inside redirects signals away from the body.

Protective case for an electronic device having a display, a first 5G antenna region on the rear surface of the electronic device, and a second 5G antenna on the side surface of the electronic device. The protective case includes a first opening providing access to the display of the installed electronic device, a first antenna region opening on the rear surface of the protective case aligned with the first 5G antenna region, providing direct access to the first 5G antenna region of the installed electronic device, and a second antenna region opening on a side surface of the protective case aligned with the second 5G antenna region providing direct access to the second 5G antenna of the installed electronic device.

A lightweight, protective case for electronic devices like phones and laptops. The case has a metal core surrounded by a plated coating that is thin enough not to interfere with wireless signals. The coating thickness is between 15 μm and 25 μm and is made of metallic and alloy oxides. This provides corrosion resistance and surface protection without adding significant weight.

A privacy enclosure for portable communication devices like smartphones that attenuates RF, sound, and light to protect user data and conversations from surveillance. The enclosure has a moveable housing that covers the device's microphones and cameras when closed, preventing eavesdropping and unauthorized recording. It also blocks RF signals from reaching the device's antennas. The housing can be opened to access the device. The enclosure can measure ambient RF levels to jam specific frequencies actively.

This Personal Communication Device (PCD) holder blocks signals to prevent disturbance in environments like courthouses or meeting rooms. The holder has walls made of conductive materials that block signals. The lid also has a conductive material, so the holder becomes signal-blocking when closed. This prevents devices like phones from ringing or vibrating in sensitive areas. The holder can be a single-compartment or a multi-compartment for multiple devices.

This mobile phone case has extended electromagnetic wave shielding to reduce radiation exposure to the user's head during calls. The case has a cover that extends beyond the phone's edges on one side. This extended portion contains a shielding material to block electromagnetic waves. This prevents radiation from reaching the user's head when holding the phone close. The extended shielding covers the side of the head where radiation would normally pass through gaps in a regular case.

Carrying case designed to protect personal items from unauthorized access and radio waves. The case has a pocket with two sides. One side is made from a material that blocks radio waves and the other side is made from a material that blocks radio waves. The pocket can be closed with a fastener to retain items inside and prevent radio waves from entering.

A protective case for electronic devices that can prevent wireless signal interference while providing good appearance and protection. The protective case has a core made of a lightweight metal like magnesium alloy, surrounded by a very thin plated coating. The coating is made of metallic or alloy oxides. This construction allows for a lightweight metal core with good appearance and protection, but avoids signal loss by using a thin non-metal coating instead of a solid metal case.

Case design for portable RF devices like smartphones with internal antennas that mitigates signal degradation when the device is enclosed in a case. The case has adapted dimensions to cover certain portions of the device's housing with different dielectric properties. It covers a section with low effect on antenna frequency characteristics, leaving a section with high effect exposed. This balances the dielectric parameters to maintain optimal antenna performance when the device is encased.

Personal data blocking device containers, such as cases for cell phones, that prevent the devices from emitting sounds or vibrations in situations where quiet is required. The cases have conductive materials that block data signals from reaching the devices inside. The cases have lids that close to completely block signals. This prevents devices from ringing or vibrating accidentally. The cases can also have features like openings for charging or data transfer when needed.

Shield for portable electronic devices like smartphones that can be configured by the user to selectively block RF signals reaching or leaving the device. The shield has a compartment to house the device and a closure element that can engage or disengage. When closed, shielding material on the closure engages with shielding material inside the compartment to block RF signals. When open, the shielding elements separate and RF signals can pass. This allows users to choose whether to block RF signals when the device is inside the shield. The shield can also have a separate compartment for the charging cable.

Protective cases for electronic devices like smartphones that have metallic structures to reduce interference with the device's antennas. The cases have features like conductively separated metallic components, dielectric insulation, and air gaps between the device and case to minimize electromagnetic interference. This prevents the metallic case from degrading wireless performance compared to bare devices. The cases also have features like hinged enclosures, latches, and sliding covers for convenience and protection.

Cell phone case called Trak-Off that prevents unwanted cell phone tracking and communication by blocking electromagnetic signals. The case has an outer shell and an inner liner made of conductive materials like metal mesh. When the phone is inserted in the case, the mesh covers the antennas and prevents signal transmission. The case allows users to easily turn off tracking and communication by simply putting their phone in the case.

Shielded enclosure for selectively allowing/disallowing communication with a contained device like a cell phone. The enclosure has an element that can switch between configurations to enable or block signals. It could be a flap, aperture cover, or removable piece. When external, signals transfer in/out. When inside, signals are blocked. The user can position the element to selectively permit/restrict device access.
