摘要:
An antenna monitoring unit for monitoring an RF transmission line and RF signal path to an antenna unit used in a distributed antenna system in a structure. The antenna is DC isolated from the RF transmission line through a current injector, allowing testing by sending a code from a base station to a remote antenna location and using a monitoring module to confirm reception of the code and transmit data to the base station relating to the antenna unit.

An antenna unit for monitoring the RF transmission line and RF signal path to an antenna unit used in a distributed antenna system. The antenna has a resistor connected to ground, and a DC injector including a capacitor having a first side connected to an RF transmission line and a second side connected to the antenna, with a first inductor coupled between the resistor and the monitoring module.

A rechargeable power cell having no voltage across its positive and negative power terminals unless the power cell is inserted into a device configured to accept the power cell is described. The power cell includes a battery management processor and battery insertion detection circuitry that cooperate to determine when the power cell is inserted into the device and then drive an electronic switch to provide for conduction of current from the power cell to the positive terminal of the cell.

Described within are systems and methods for transliterating and translating source non-Romanized language text strings from a plurality of electronic sources to Romanized target language text strings by converting the source non-Romanized language text strings to a standard document encoding format, splitting the source non-Romanized language text strings into smaller units, transforming the smaller units into entity profiles, processing the entities profiles with data from external databases, translating the entities in the entity profiles into a Romanized target language, and outputting the entities into a plurality of data formats for external systems.
摘要:
Systems and methods are provided for the detection of conductive bodies using three-component electric or magnetic dipole transmitters. The fields from multiple transmitters can be combined to enhance fields at specific locations and in specific orientation. A one- two- or three-component receiver or receiver array is provided for detecting the secondary field radiated by a conductive body. The data from multiple receivers can be combined to enhance the response at a specific sensing location with a specific orientation. Another method is provided in which a three-component transmitter and receiver are separated by an arbitrary distance, and where the position and orientation of the receiver relative to the transmitter are calculated, allowing the response of a highly conductive body to be detected.
摘要:
A technique and apparatus to provide status tracking of presence and/or location of wireless devices to requesting entities inside and/or outside a particular wireless system. Presence and/or location information is provided to entities outside a particular servicing wireless network via mechanisms of call processing components of a mobile network and standard mechanisms available to any appropriately conforming MSC element. In one embodiment, a wireless chat automatic status tracking system utilizes a change in mobile registration status to automatically forward or copy a registration notification (REGNOT) message to an external IP application, to notify a chat group system outside the wireless network of current status information activity regarding a relevant device. Change in mobile registration is communicated via a suitable signaling link between a HLR and the chat group system. REGNOT messages are pushed over TCP/IP connections to external applications to automatically notify the external system of a particular user's location.

An intelligent rechargeable battery pack having a battery management system for monitoring and controlling the charging and discharging of the battery pack is described. The battery management system includes primary and secondary protection circuits for monitoring the charging and discharging of the battery. Individual battery cells forming the battery pack are connected by a main bus to a connector for connection to a battery charger or a device to be powered, and the main bus may be interrupted by a switch controlled by the battery management system to prevent damage to the battery during charging or discharging of the battery.
