Abstract:

A wearable heart rate monitor includes a wrist cuff or strap suitable for being placed about the wrist of a person, a display housing mounted on the wrist cuff, a pressure transducer element also mounted on the wrist cuff at a position to cover the radial artery when the wrist cuff is placed about the wrist, and logic circuitry disposed in the display housing for producing an indication of the pulse rate of the individual wearing the wrist cuff. The pressure transducer element detects expansion and contraction of the radial artery and applies a signal to the logic circuitry which then produces a visual display of the pulse rate.

Abstract:

A timing control circuit for use in automatically and intermittently operating electrical appliances, such as lamps, for security purposes in homes, offices and other buildings. The circuit is adapted to plug into a conventional wall socket and to receive conventional two-prong plugs of electrical appliances. When enabled, the circuit intermittently applies power from the wall socket to a connected electrical appliance so that the appliance is turned on and off automatically over some period of time. The circuit includes manually operable switches to enable a user to select the intermittency or on-off pattern of operation of the appliance and the period of time over which such pattern is developed. Controlling turn-on and turn-off of lamps, radios, or the like gives the appearance of occupancy of a dwelling and therefore discourages would be burglars and prowlers.
