摘要:
A clock comprises an alarm clock housing having a front face, a clock display occupying at least a portion of the front face, a control on the housing for activating a shade positioning function, and a processor within the housing. The processor is responsive to the control for generating at least one shade positioning command to be transmitted to at least one motorized window shade, so as to cause the motorized window shade to move to one or more position at one or more corresponding predetermined interval relative to an alarm time.

A window shade alarm system for gently awakening a user. The window shade is connected to the Internet and opens such that light gradually increases in a room. Thus waking a user less abruptly than a traditional audio alarm. The window shade stores user selected modes and can control wireless enabled lights within a room to simulate the gradual increase of light at sunrise. The alarm system is connected to remote activated devices for the convenience of the user.

In the illustrated embodiments, a rotary position encoder is manually positioned to select any of a set of x-ray exposure times to be used in making medical x-ray photographs. In one form, the encoder output selects a code word from a read only memory, and a comparator ends the timing cycle when a counter reaches a count value corresponding to the active code word. The pulse generator supplying input pulses to the counter, rather than operating at a constant rate, may be controlled so that the pulse count per unit time corresponds to a specified mAs-product, an x-ray tube being switched off when a selected count value (corresponding to a desired mAs-product) is reached.

The method, and apparatus therefor, for processing calls transmitted at random from calling devices, each call specifying a response delay before such call should be processed, wherein the calls are chained into a waiting queue as they are detected, and wherein the calls in the queue are processed according to their specified response delays.
摘要:
An automatic aerosol dispenser for producing periodic discharge from an aerosol container at long, accurately determined time intervals on the order of 15 minutes or more and which is completely self-contained, operating on low battery voltage on the order of 3 volts. The time interval is determined by an RC circuit having a long-time constant, with a transistor detectoramplifier, including feedback, for initiating a cycle of motor rotation. The capacitor of the RC circuit is restored to reference condition in an RC circuit of short-time constant. An electromechanical driving arrangement is disclosed which is particularly suited for low-voltage operation.
