Abstract: A personal alarm system can help a user to wake up in a preset time. A sensor can sense operations of the personal alarm system and output sense signals. A control unit can calculate a sum of the sense signals to obtain a number of operations of the personal alarm system, and stop an alarm from sounding in response to the sum of the sense signals meeting the condition to stop the alarm from sounding.

Abstract: An alarm that uses a floor situated apparatus so that when the alarm goes off, the user must place their feet on the apparatus for a predetermined period of time to deactivate the alarm. The alarm sequence optionally provides that the apparatus cover may be translucent and/or transparent with a plurality of illuminable elements thereunder providing an alarm visual display. Also provided is a remote control for actuating a projected display of time onto the wall. The apparatus is also a scale for displaying the user's weight. The weight requirement for deactivating the alarm can extend from placing the feet on the apparatus while still in bed or require the user to stand on the apparatus for said period of time. Further provided for is the removal of the alarm clock portion from the floor apparatus.

Abstract: In a microwave oven, a turn table rotates once in a period TX. During one rotation of turn table, a control circuit usually detects six pulse signals. Control circuit detects a weight of food placed on turn table based on detected intervals TA, TB, and TC of pulse signals. Note that, if six pulse signals are not detected during one rotation of turn table, the control circuit retries detection of the pulse signals and detects the weight of food placed on turn table based on TA, TB, and TC for a subsequent rotation of turn table.

Abstract: A weight monitoring apparatus which is suitable for use in a computerized control system and which provides a visual net relative weight indication, as well as an alarm, indicative that an alarm level weight is being approached by the article being weighed.

Abstract: Apparatus is disclosed for the testing and fitting of cross-country skis including means to support the cross-country ski having sensor means distributed along its length and width adapted to emit a signal when the bottom surface of the cross-country ski presses them, display means adapted to indicate the origin of the signals from the sensor means and adjustable loading means to exert predetermined forces to points along the top surface of the ski and load measuring means adapted to indicate the applied load.

Abstract: An intravenous alarm device provides an alarm signal to indicate that a predetermined amount of liquid remains in a liquid dispensing container of the type such as an I.V. bottle or bag adapted to be suspended from an arm. The device includes an attitude-sensitive transducer such as a mercury switch defining a reference axis, and the alarm signal is given when the reference axis extends along a line in predetermined angular relationship with the horizontal. The device further includes a structure supporting the transducer, with the structure including, at a first point thereof, a hanger portion to suspend the device from such an arm; at a second point thereof, a holding portion to suspend the container from the device; and, at a third point thereof, a device center of gravity. The first, second, and third points are spaced to define vertices of a triangle.

Abstract: A monitoring device which monitors the extent of infusion of intravenous solutions and provides an alarm signal when such infusion has progressed to a predetermined degree. The device comprises a cylindrical container to which is coupled, at its upper end, an attaching member for suspending the device from an intravenous solution supporting stand. Peripherally disposed about the cylindrical container are electrical sockets adapted such that each socket may accept an associated electrical plug. Extending through and below the lower end of the cylindrical container is a suspension member having a hook section for suspending an intravenous solution container. A helical spring is disposed within the cylindrical container, coaxially surrounding that portion of the suspension member which extends into the cylindrical container. The vertical position of the spring is defined by the lower internal end of the cylindrical container and by the upper extremity of the suspension member disposed within the container.

Abstract: Weighing apparatus for grading articles such as eggs and the like according to their weight. The apparatus comprises a tray, and a pair of leaf springs for mounting the tray for up and down movement and operatively connected to the tray and a support member, and being deflectable generally downwardly relative to the support member a first distance responsive to article weight. A stop is provided for allowing downward deflection of the tray relative to the support only to a second distance, which is normally less than the first distance. An out-of-round cam or the like changes the relative position of the stop and the support member so that the second distance approaches the first distance, and electrical contacts, photoelectric apparatus, or the like, are provided to sense when the second distance is substantially equal to the first distance.

Abstract: A device for supporting a patient, having a carrying member and a horizontally extending lying support for the patient, with a motor for varying the distance between the support and a medicinal unit. The invention is particularly characterized by the provision of a spring scale between the patient support and its carrying member, having a switching member which can be shifted corresponding to the weight of the patient. Switching means are connected with the switching member for interrupting the current circuit of the motor, the distance between the switching means and the switching member being adjustable.
