  • Publication number: 20160058606
    Abstract: A system (10) and method for use by a subject with a sleep disorder, such as nocturnal enuresis. The system (10) comprises at least one sensor (11) that detects at least one attribute of the sleep disorder, for example urine, and outputs at least a first signal on or after detection of that attribute. The system (10) further comprises a control device (12) that comprises an arousal device (14), such as a loudspeaker, that activates on or after receipt of the first signal, an interactive device (15) that is actuable by the subject to deactivate or modify the operation of the arousal device (14) and an output device (16) for delivering an output to the subject. The output being delivered on or after deactivation or modification of the arousal device (14).

  • Patent number: 3985142
    Abstract: A heart pacer providing heart stimulating electrical impulses in the absence of naturally occurring heartbeats, together with means to prevent inhibition of the electrical impulse in the presence of electrical interference signals of either physiological or nonphysiological origin. Logic functions are incorporated to detect the presence of any sensed signal occurring after a first predetermined time but earlier than a second predetermined time, both measured from the preceding detected signal which may be either a natural heartbeat, a stimulating electrical impulse, or an interference signal. The first predetermined time interval is greater than the time duration of the electrical manifestations of a single heartbeat while the second predetermined time interval is less than the interval between two natural heartbeats. Sensed signals are delayed before triggering the demand function.

  • Patent number: 3983881
    Abstract: An improved muscle stimulator, particularly suited to long term rhythmic stimulation for the selective development of musculature otherwise asymmetric or retarded in relative development. To minimize the subjects' awareness of stimulation, to permit nocturnal use, and to minimize battery consumption, the energy content of each pulse train is modulated by a progressive increase of pulse width up to a maximum, followed by a progressive decrease of pulse width, thus yielding a gradual contraction and relaxation of the muscle.

  • Patent number: 3972334
    Abstract: A heart pacer providing heart stimulating electrical impulses in the absence of naturally occurring heartbeats, including two electrical impulse generating time bases each capable of emitting heartbeat stimulating impulses. A sensed signal, accepted against criteria preceding it in time, as a valid heartbeat signal rather than an interference signal, serves to reset one time base while a second time base continues its cycle on the assumption that the sensed signal is an invalid or interference signal. If further signals are sensed, within criteria indicating that the original sensed signal was, in fact, invalid, the second time base continues its cycle until it emits a heart stimulating impulse at which time the first time base timing cycle is cancelled. If, however, the original sensed signal is not shown to be invalid the output of the second time base is suppressed and the reset timing cycle of the first time base continues.
