摘要:
A multi-portion housing for a portable terminal having a proximal end, a distal end, a back surface, and a front surface, the front surface configured for mounting a user interface between the proximal and distal ends. The multi-portion housing comprises a central housing portion providing a rigid body extending between the proximal and distal ends for facilitating rigidity of the multi-portion housing to inhibit deformation of the multi-portion housing, the central housing portion having an upper surface and an opposing lower surface. A second housing portion is secured to the central housing portion and has a first resilient seal positioned between a first mating surface of the second housing portion and a corresponding mating surface of the central housing portion, the corresponding mating surface of the central housing portion extending only partway between the proximal and distal ends and being positioned on either the upper or the lower surface. A third housing portion (e.g. an endcap) is secured to the second housing portion and has a second resilient seal positioned between a second mating surface of the second housing portion and a corresponding mating surface of the third housing portion. The first resilient seal and the second resilient seal are configured for inhibiting penetration of foreign contaminants into an interior of the multi-portion housing.

A method and a system for configuring of a client device using a configuration device in a peer to peer communication local network including a plurality of client devices, the configuration device including configuration information designated as sharable information. The method comprises generating a discovery request at the configuration device, the discovery request targeted to the plurality of handheld devices, in response to the discovery request, generating a request for communication with the configuration device from at least one client device, establishing communication between the configuration device and the client device, assigning, at the configuration device, a group to the at least one client device, identifying, at the configuration device, a selection of components from among the sharable information, the selection of components associated with the assigned group and for downloading to the at least one client device; and downloading, for installation at the client device, the selection of components to the at least one client device of the assigned group.
摘要:
A system and method for externally controlling the charging of a battery powered mobile computing device includes a charging unit configured to be electrically coupled to the mobile computing device to charge a battery therein. The charging unit comprises a charger configured to operate in a first mode to provide a constant charge current to the battery to be charged and to operate in a second mode to provide a constant charge voltage to the battery to be charged and where the switch from the first mode to the second mode occurs when the voltage at the battery a predefined threshold voltage. The charger including an offset compensator configured for applying an offset voltage to the measured output of the charger to maintain the charger in the first mode to compensate for voltage drops between the charger and the battery thereby allowing the battery voltage to reach the threshold voltage.
摘要:
A method, apparatus and system are described for adjusting the frequency of one or more clock signals used by a device. The one or more clock signals are adjusted by a determined amount when a channel quality metric of an RF channel in use by the device indicates a degradation in the reception quality. A radio frequency channel quality metric (RF metric) of a radio frequency channel in use is monitored by a device; a clock signal used by a clocked component of the device is determined as a target clock signal to adjust when the RF metric violates a threshold; a clock adjustment is determined to apply to the target clock signal; a rate of the target clock signal is adjusted according to the clock adjustment; followed by a step of returning to monitor the RF metric of the radio frequency channel or an RF metric of another radio frequency channel in use by the device.
摘要:
A system and method are described for displaying battery information on a display of a portable computer. After powering on the portable computer, battery information of a battery of the portable computer is retrieved. The retrieved battery information is displayed on the display of the portable computer and the operating system (OS) loaded into an executable memory of the portable computer is executed after the display of the battery information.
摘要:
A method and apparatus for an impact resistant touchscreen display module, such as for use in ruggedized mobile computing and display devices. The structure provided also allows for severability of the touchscreen and display screen portions, enhancing the practicability of replacing individual components for repair of a damaged touchscreen display module.
摘要:
A microstrip antenna, such as an internal patch antenna with circular polarization diversity, configured for at least one of transmission or reception of electromagnetic waves, such as in the UHF spectrum, with respect to a surrounding environment. The antenna comprises: an antenna element isolated from an electrical ground of the antenna and configured for operating as a radiating surface for the electromagnetic waves with respect to the surrounding environment; a transmission line having a pair of electrical conductors such that a first conductor of the pair of electrical conductors is connected to the antenna element and a second conductor of the pair of electrical conductors is configured for coupling to the electrical ground, such that the transmission line is configured to conduct current flow for at least one of towards the antenna element for transmission of the electromagnetic waves from the antenna element or away from the antenna element as a result of reception of the electromagnetic waves by the antenna element; and a composite substrate having a selected dielectric constant including a plurality of individual dielectric material layers in a stacked layer arrangement, such that the composite substrate is positioned between the antenna element and the electrical ground and the antenna element is attached to a first surface of the composite substrate. Further, an optional ground element can be attached to the other side of the composite substrate and the tuning of the antenna can be dual band in the UHF or higher frequency spectra.
