Wireless Medical Sensor comprises the circuitry for both vital sign measurements and short-range RF transmission, and means for measuring and interpreting a patient's vital signs, modulating and transmitting wireless signal back to Short-Range RF Receiver through a short-range RF network. System Software of the Wireless Communication and Global Location Enabled Intelligent Health Monitoring System resides in System Processor and includes Intelligent Controller , which comprises Task Control Administrator , and a plurality of Task Shared Memory . Task Control Administrator manages and controls the execution of Two-Way Wireless Communication Task , Global Position Data Acquisition Task , Panic Button Task , HTTP Request Processing Task , Patient Vital Sign Processing Task , Adaptive Location Assessment Task , On/Off Button Task , Alert Beeper Activation Task , Battery Management Task , and Wireless Medical Sensor Decoding Task . All application tasks of System Software are running under separate parallel execution threads. Under an urgent situation, the two-way wireless communication, global position data and adaptive location assessment capabilities allow an Emergency Service Vehicle to be dispatched to the patient that carries the system. The system also includes a HTTP Web server that can respond to a remote request sent wirelessly either from a patient monitoring station or a patient's family member through a standard Internet browser, anywhere and anytime. The system uses a rechargeable/removable battery in conjunction with a software control to recharge the system and conserve system's power consumption.

International Classification:

US Classification:

320167

Abstract:

An energy-reclamation apparatus of the present invention including at least a supercapacitor element connected with a charging source and a controlled circuit. After the supercapacitor element is charged to the potential of the charging source, the supercapacitor element and the charging source will work in series to conduct a repetitive polarity reversal of the supercapacitor element through a controlled circuit. As the supercapacitor element discharges, it is reversely charged concurrently. In other words, while the voltage of the supercapacitor element is decreasing on the side, a negative potential is complementarily developing on the other side. By repeatedly reversing the polarity of the supercapacitor element, more energy from the serially connected charging source can be reclaimed and reused.

Abstract:

A fax message record/relay device or system operates in conjunction with a local fax machine. The system allows the local fax machine to operate normally while the record/relay device simply records incoming fax messages and stores them in a memory. An authorized person may call in to the record/relay system and request that the fax messages be forwarded to a telephone number corresponding to a fax machine which the authorized person has immediate access to. The authorized person uses a password and a DTMF push button telephone in order to remotely input commands to the record/relay system.
