Abstract: A universal radio frequency identification reader and emulation handheld device and system configured to read and emulate radio frequency identification tags in the low frequency, high frequency, and ultra-high frequency spectrums. The system may include a mobile or a web application to control and interact with the handheld device. The mobile application may receive an identifier of an RFID tag, upload the identifier to a server, determine, via the server a chip/identifying number of the RFID, and command an RFID emulator to emulate an RFID tag based on the received chip/identifying number.

Abstract: A universal radio frequency identification reader and emulation handheld device and system configured to read and emulate radio frequency identification tags in the low frequency, high frequency, and ultra-high frequency spectrums (from 30 kHz to 1050 MHz). The system may include a mobile or a web application to control and interact with the handheld device. The system may allow for the saving of radio frequency identification tag information in cloud infrastructure for later emulation.

Abstract: An electronic device includes a casing, a circuit board, a panel module, a first backlight module set, a second backlight module set and a control unit. The circuit board is disposed inside the casing and installed with a first operating system and a second operating system. The panel module is installed on the casing and has a first icon pattern set and a second icon pattern set. The first backlight module set corresponds to the first icon pattern set. The second backlight module set corresponds to the second icon pattern set. The control unit controls the first backlight module set to illuminate the first icon pattern set when the first operating system is executed, or controls the second backlight module set to illuminate the second icon pattern set when the second operating system is executed.

Abstract: A portable electronic device includes a casing with a casing pivotal portion and a key device. The key device is installed on the casing and includes a button cap. The button cap includes a cap pivotal portion, a first cap body and a second cap body. The cap pivotal portion is pivoted to the casing pivotal portion. The first cap body extends from the cap pivotal portion along a first axis. The second cap body extends from the first cap body along a second axis. The button cap rotates in an activating direction when the first cap body is applied by an external force along the first axis or when the second cap body is applied by the external force along the second axis.

Abstract: An electronic device includes a battery module, a casing and a latching mechanism. The battery module has at least one battery retention tab. A battery compartment is formed on the casing. The battery module is detachably installed in the battery compartment, and the casing has a stopping structure. The latching mechanism is slidably installed on the casing and includes a latching cover, a lock member and a resilient member. The latching cover is installed on the casing in a slidable manner. The lock member is pivoted to the latching cover. The resilient member is installed on the latching cover. When the latching cover slides to the lock position, the resilient member forces the lock member to engage with the stopping structure, so as to fix the latching cover in the lock position.

Abstract: A cover for a device is disclosed. The cover may include a first portion operable to protect a button of a device from inadvertent actuation, wherein the first portion enables viewing of the button while the cover overlaps the device. The cover may also include an opening operable to afford access to an interface component of the device, wherein the opening is operable to enable a user to reach through and physically interact with the interface component while the cover overlaps the device. The cover may further include a second portion enclosing the opening on all sides.

Abstract: A cover for an electronic device made of a transparent material and having a form factor that protects function buttons of the device from inadvertent actuation. The cover has an opening of a size, shape and location to afford access to an interface device for multi-way navigation with the cover in place. Protrusions in tabs at the sides of the cover snap into cutouts located midway along the side of the electronic device and may be used to hold the cover in place. The cover may be stored on the back of the device while the device is in use. The transparent nature of the cover affords viewing of a display screen with the cover in place.

Abstract: A housing for a portable hand held device such as a palmtop computer uses a torsional latching system. The housing is made of front and rear housing laminated housing members. The torsional latch arrangement works in conjunction with a plurality of latch fingers along the edge to attach the front housing laminate with the rear housing laminate. The torsional latch arrangement has a pair of L-shaped latch ribs that engage with a T-shaped latch member by torsion of the L-shaped latch ribs into engagement with pockets adjacent the T-shaped latch member prevent movement of the two housing laminates in relation to one another.

Abstract: An expandable and contractible stylus for interfacing with a touchscreen of an electronic device. The expandable and contractible feature allows for a stylus that contracts to fit into a stylus holder in a small handheld device and expands to facilitate its removal from a device and to fit more comfortably in a user's hand. It holds either its expanded or contracted position for any orientation in space. An expandable and contractible stylus may facilitate the user's experience and thus provide an advantage over other conventional styluses.

Abstract: A drip-proof switch cover for covering an electrical box having a wall switch with an actuator protruding through the cover, wherein a collecting reservoir is disposed at the lower end of the cover to collect liquid drippings from the hand of a user during actuation of the switch actuator.

Abstract: A laminated housing for a portable hand held device such as a palmtop computer. A metal front cover is bonded with a thermoplastic adhesive to a plastic midframe to form a front housing laminate. A metal rear housing member is bonded with a pressure sensitive adhesive to a plastic substrate to form a rear housing laminate. A latch arrangement including a plurality of latch fingers along the edge attach the front housing laminate with the rear housing laminate. A latch arrangement having a pair of L-shaped latch ribs that engage with a T-shaped latch member by torsion of the L-shaped latch ribs into engagement with pockets adjacent the T-shaped latch member prevent movement of the two housing laminates in relation to one another.

Abstract: A vibrator motor mount for an axisymmetric vibrator is mounted directly on a PCB or other mounting surface and includes a clip for holding the vibrator and a spring type connector. The clip and the vibrator make contact and establish a first electrical connection. The spring type connector makes contact with an end of the vibrator establishing a second electrical connection. The spring type connector and clip are electrically isolated and provide positive and negative electrical contacts for operation of the vibrator. Portions of the vibrator held by the clip and an end of the vibrator that contacts the spring type connector are also electrically isolated and are attached to the internal electronics of the vibrator.
