Abstract: A mobile equipment service device for use by non-ambulatory persons. The device can be a manually movable commode for permitting such persons to independently access a system to contain waste, seal the waste, prevent odors for emanating into the room, and permit later removal and disposal of the waste. The system may also introduce an odor absorbent material into the sealed area where the waste is retained. In a further embodiment, a programmable device, such as a commode, can be remotely operated by the person, increasing the person's ability to independently access and use the device by moving the device to and from that person, and then securing that device to permit safe use by those persons. Preferably, the programmable device is battery powered so as to be self-propelled. In addition, the device contains a data collection system that collects data on use, and transmits that data as directed to location.

Abstract: A miniature vibrator (50) for a wrist (10) worn alerting device (20) such as a pager produces a rocking motion vibratory alert. The vibrator (50) has a pair of cantilevered piezoelectric resonant vibrators (62, 64, 66 and 72, 74, 76) which are driven by separate drivers (34, 38) at a frequency determined by a frequency generator (32) but at opposite phases because of an inverter (36). Since the vibrating masses (64, 74) move in opposite directions (200, 210), translational movement of the alerting device (20) is substantially eliminated and a resulting rocking motion produces an improved vibratory sensation on the wrist (10) of the user. Additionally, driving the resonant vibrators (62, 64, 66 and 72, 74, 76) at opposite phases results in reduced surge currents (150) on the battery (40).

Abstract: A detector circuit (301) is utilized in a DC to DC converter (300) having an inductor (356) coupled to a switch (358) for interrupting an electric current through the inductor (356), thereby allowing the inductor (356) to transfer stored energy to a capacitive load (364). The detector circuit (301) includes a capacitor (302) coupled to the inductor (356) for generating a transient current (428) in response to a completion of a transfer of stored energy from the inductor (356). The detector circuit (301) further includes a reference current generator (306) for generating a reference current, and a summing node (304) coupled to the capacitor (302) and coupled to the reference current generator (306) for summing the transient current (428) and the reference current. The two summed currents form a transient control current (436) responsive to the completion (424) of the transfer of stored energy from the inductor (356).
