Abstract: The device includes a housing fastenable to a subject's upper arm wherein housing and upper arm have parallel longitudinal axes. The housing accommodates a control circuit including a processing unit, a physiological sensor and an acceleration sensor for providing a sensor signal and an acceleration signal, respectively to the processing unit. The processing unit includes an evaluation function for evaluating the sensor signal and providing a detection signal, a generator function generating a signal indicative of an occurrence of an epileptic seizure from said detection signal, a posture determination function using the acceleration signal and arranged within the housing for establishing an angle between the housing's longitudinal axis and a gravity vector, and for determining whether the angle is within a predetermined range corresponding to the upper arm lying down. The evaluation function further reduces a sensitivity of evaluating the sensor signal when the angle is within the predetermined range.

Abstract: Photoplethysmographic device for measuring a heart rhythm, comprising a housing having a contacting surface and a control unit, a photoplethysmographic sensor mechanically attached to the contacting surface and connected to the control unit, wherein the control unit is arranged to receive a photoplethysmographic signal from the photoplethysmographic sensor, a fastening band having a first end and a second end, the first end and second end attached to the device for attaching the device to a subject with the contacting surface contacting the subject's skin, a pressure sensor attached to the contacting surface in close proximity to the photoplethysmographic sensor. The control unit is arranged determining whether the pressure from the pressure sensor is in a range suitable for photoplethysmographic measurement by the photoplethysmographic sensor.

Abstract: A circuit for blocking reception of in-band frequency-shift keyed (FSK) signals by the reception transducer of a telephone subscriber terminal without requiring muting of the reception transducer. The incoming telephone reception signal, which contains both voice and frequency-shift keyed (FSK) signal components, is processed, e.g., within a digital signal processor (DSP), such that the FSK signal component is substantially cancelled. The incoming telephone reception signal is processed to extract amplitude, frequency and phase information, as well as to recover the FSK data clock. This FSK signal information is then used to generate a replica FSK signal for summing with the incoming telephone reception signal to cancel the FSK signal component.
