International Classification:

H04B 138

US Classification:

455569, 455563, 455557, 455 90, 455556

Abstract:

Wireless communications relative to a vehicle using a wireless communications device, a pocket for holding the wireless communication device and an interface module in communication with the pocket are provided. The pocket can include a processor for translating communications between the wireless communications device and the interface module. The interface module has processing capability and can communicate with different pockets and thereby different wireless communications devices. In at least one embodiment, the interface module manages voice recognition and text-to-speech commands to facilitate hands-free communications in the vehicle. The interface module can function as a communications hub involving a number of vehicle subsystems. In a preferred embodiment, the vehicle subsystems are separately addressable using the interface module and/or other processing hardware/software. However, in communicating over the Internet, a vehicle IP address is utilized.

International Classification:

A61B 5/02

US Classification:

600502000

Abstract:

A heart rate monitoring system for use in sport and fitness training that includes a sensor belt worn on the waist of the user and a display device worn on the wrist of the user. The sensor belt has a pair of sensors that can be located on opposite sides of the body in various locations, such as near the kidneys, near the ilium bones in the pelvis, or on the front abdominal area of the user. Various signal processing techniques are employed to extract the degraded signal that is available at the waist area as compared to the chest area. These signal-processing techniques include bandpass filtering, an adaptive time window, a delayed transmission to allow for correction methods such as missed beat replacement and extra beat deletion, a lead off detection and adjustment algorithm, automatically adjustable gain control, and waveform detection and characterization.

International Classification:

H02H 300

US Classification:

361 42

Abstract:

A ground fault interrupter, operable in a measurement state, is employed with a DC circuit having a DC power source and a load. The DC source supplies DC current to the load along a supply current path and receives DC current from the load along a return current path. The ground fault interrupter comprises a first resistance in series with the supply current path, a second resistance in series with the return current path, and a current interrupter disposed in series with one of the current paths. The current interruptor interrupts the one of the current paths in response to actuation of the current interrupter. The ground fault interrupter further includes a measurement unit for measuring voltage drops across the respective first and second resistances during the measurement state, obtaining a measurement value using a difference between the voltage drops, and comparing the measurement value to a predetermined threshold. The measurement unit is constructed and arranged to actuate the current interrupter in response to the measurement value exceeding the predetermined threshold.

G16H 80/00
G16H 40/63
G16H 40/67
A61H 31/00

Abstract:

The present invention relates to a device, and software and methodology associated with a portable Automated External Defibrillator (“AED”). The portable AED works with a mobile device and software, and includes two or more cardiac pads, a battery pack, and specialized capacitor. When connected to a patient in cardiac arrest, the AED contacts Emergency Medical Services, and records patient information to be transmitted for evaluation by medical providers. The AED is able to analyze cardiac rhythms, suggests administering one or more shocks to the patient in appropriate cardiac arrhythmia, and guides a user on proper CPR technique, if enabled. The AED software can alert other personnel via a mobile device app.

Abstract:

An electrosurgical system is disclosed. The system includes a radio frequency output stage configured to output at least one radio frequency waveform and a current sensor coupled to the output stage and configured to output a first differentiated signal corresponding to a current of the at least one radio frequency waveform, the current sensor coupled to a first conditioning circuit configured to integrate the first differentiated signal to output a processed current signal indicative of the current. The system further includes a voltage sensor coupled to the output stage and configured to output a second differentiated signal corresponding to a voltage of the at least one radio frequency waveform, the voltage sensor coupled to a second conditioning circuit configured to integrate the second differentiated signal to output a processed voltage signal indicative of the voltage, wherein the first and second conditioning circuits have a substantially similar bandpass and phase response.
