A passively re-radiating cell phone sleeve assembly capable of receiving a nested cell phone provides signal boosting capabilities. Signal boosting is enabled by use of an additional antenna, a pass-through repeater, dual antenna isolation capability and other features.

An antenna for a mobile phone and a mobile phone having the same are provided. The antenna for a mobile phone includes: a metal mobile phone case provided with a first slot and a second slot intersecting with the first slot; a circuit board having a clearance zone and a parasitic branch stretching into the clearance zone, and disposed within the metal mobile phone case; an exciting sheet disposed between the circuit board and the metal mobile phone case, and across the first slot in a width direction of the first slot; a dielectric filler disposed between the exciting sheet and the metal mobile phone case, and configured to fill the first slot and the second slot.

An electrical connector includes: an upper and lower terminal modules each including plural terminals; a metallic plate secured between the upper and lower modules; a metallic bracket accommodating the secured metallic plate and upper and lower terminal modules; and an insulative body insert-molding the metallic bracket with the secured metallic plate and upper and lower terminal modules to form a tongue exposing the terminals of each of the upper and lower terminal modules. The metallic bracket contacts the metallic plate and borders the tongue.

A wireless pocket transmitter having a rear side, a front side and a receiving compartment for a rechargeable battery. The receiving compartment has a rear wall which at least partially forms a part of the rear side, two side surfaces and a connecting portion with electrical contacts. The two side surfaces are each coupled with a first side to the rear wall and with a first end to the connecting portion. The second ends of the side surfaces each have a respective guide for the battery. The guides do not extend along the entire length of the side surface and the guide has two projections and a passage therebetween.

This electronic device includes a wearing detector, provided at a position that comes close to or in contact with a human body when the electronic device is worn by a user, that detects wearing of the electronic device by the user, an antenna that transmits radio waves, and a controller that restricts transmission of radio waves from the antenna when wearing is detected by the wearing detector.

The present invention embodiment provides a terminal cover body and a terminal, said terminal cover body being used for covering the device body of the terminal and encapsulating electronic components on the device body. The terminal cover body comprises: a casing body, wherein a slide-groove is provided in the casing body and a slide-block is provided in the slide groove; a lock engagement component which comes into contact with the slide-block; pushing the slide-block causes the lock engagement component to move between a first state and a second state, wherein, in the first state the lock engagement component is engaged with the device body and the casing body is tightly connected to the device body; in the second state, the lock engagement component is detached from the device body and the casing body can be separated from the device body.

A guest engagement system and associated methods provide seamless engagement with guests of facilities through the use of wireless sensing technologies. The system makes use of individual guest devices which are carried by guests and used to automatically identify and authenticate the guests throughout the facility. Services can thereby be seamlessly provided to the guests throughout the facility. The services include contact tracing, automatic unlocking of doors, including hotel or state room doors, based on the guests' immediate proximity to their assigned room's door. The services also include automated payment services provided at checkout or vending terminals, and automated log-on to interactive displays and portals, among others, based on secure wireless authentication of the guest devices. The guest devices can each include a device health sensor configured for measuring at least one health function of a user wearing the guest device.

A system for providing controls signals to a wireless remote camera comprises a signal generating device that presents forward and inverse polarity pulse trains. A transmitter data converter circuit has a forward polarity input point for receiving the inverse polarity pulse trains and an inverse polarity input point for receiving the forward polarity pulse trains, and converts the forward and inverse polarity pulse trains to a conditioned unitary pulse train. A modulator circuit modulates the conditioned unitary pulse train onto an RF carrier. A demodulator circuit demodulates the modulated output wave to produce a reproduction of the conditioned unitary pulse train. A receiver data converter circuit converts the conditioned unitary pulse train to conditioned forward polarity pulse trains and conditioned inverse polarity pulse trains. A camera control circuit produces control signals based on the conditioned forward and inverse polarity pulse trains. A wireless remote camera receives the control signals.
