摘要:
It is described herein a system for disinfecting a point-of-sale terminal. The system may comprise a housing and at least one light source. The housing may be configured to connect to a first exterior surface of the point-of-sale terminal with the at least one light source mounted within a hollow interior of the housing. The at least one light source may be configured to project light in the ultraviolet spectrum of between 100 nm and 400 nm at a first angle relative to a first plane of the point-of-sale terminal upon receiving an electrical signal from a switching mechanism. The first angle may be in the range of between 0° and 90°.
摘要:
A method for determining a geospatial location of a client in signal communication with a wireless array is provided. A magnetometer is used to provide geospatial orientation information relating to an orientation of a wireless array relative to the surface of the Earth. The geospatial orientation of the wireless array is determined based on the geospatial orientation information provided by the magnetometer. A transceiver in the wireless array that the client is in signal communication with is identified. The geospatial orientation of the transceiver that the client is in signal communication with is identified based on the geospatial orientation of the wireless array and the position of the transceiver in the wireless array. A geospatial direction of the client relative to the wireless array is calculated based on the geospatial orientation of the transceiver the client is in signal communication with and is used to identify a geospatial sector in which the client is located.

A wireless array for providing access to a network is provided. The wireless array includes at least two transceivers in signal communication with a client. A magnetometer of the wireless array provides orientation information relating to an orientation of the wireless array relative to a magnetic field. A controller of the wireless array is in signal communication with the transceivers and the magnetometer. The controller manages the communications exchanged via the transceivers and receives the orientation information provided by the magnetometer.

In one embodiment, an integrated antenna and display shade for a wireless portable control unit is provided which includes a stowable display shade having two side panels and a front panel between the two side panels. Each of the two side panels are foldably connected to opposing edges of the front panel so as to be capable of folding into planes generally parallel with a plane of the front panel when stowed and into planes generally orthogonal to the plane of the front panel when deployed to shade a visual display. The front panel includes an active antenna and each of the side panels include a parasitic antenna.
