A push button panel, which has a transparent panel main bodyfor allowing a screen image on a display surfaceto be visually seen, is disposed for each void partbetween opaque framesof a lattice paneldisposed on the display surfaceof a monitor. Extended partsare disposed at the four corners of an outer circumference of the push button panel, such that they are extending outwardly in the diagonal directions, and these extended partsare fitted to recessed partsprovided at the four corners of an void partof the lattice panel. A rubber contact, in which electrodes functioning as detecting means are embedded in an elastic body functioning as supporting means, is disposed at a lower surface side of each extended part

Input device for game machine

An interface unitfor a game machineincludes a monitorhaving a single display surface, and an input moduleserving as an input device overlaid on the display surface, wherein a plurality of push button panels, each of which has a panel main body with enough transparency to allow a screen image on the display surfaceto be visually seen, partitions the unitinto input display parts, which are arranged on partial regions of the display surfacein a push-down operable manner, and a multi purpose display partfor displaying a screen image with a different purpose from that of the input display parts

Positions of a plurality of objects in a space are detected. A position of reflected light of an object passing through an infrared screen is specified by analyzing an image obtained by selectively imaging the infrared rays. When the infrared screen is formed in front the display, reflected light is only caused just in front of the display. When the infrared rays are selectively imaged, a picture displayed with visible light is separated from reflected light in the infrared region, and only the reflected light can be imaged. A position of the reflected light on the display can be specified by a publicly known image analysis technique.

A variable attenuation device is provided for an antenna amplifier by providing high attenuation and low attenuation signal flowpaths connected to the amplifier input by respective pin diodes. The biasing of the diodes and, thus, the attenuation factor provided, is controlled in proportion to the output of a rectifying circuit which, in turn, provides a DC output proportional to the magnitude of a given polarity of the AC signal supplied to the amplifier from inside the subscriber's home.

In an alarm system utilizing a bidirectional wired television system, a large number of subscribers are located in a plurality of group units, whereby first specified frequencies which are common to respective of the group units but are different for the subscribers in each group unit are assigned to the respective subscribers in the respective group units to which are assigned another second specified frequencies which are different from one another, and still another third specified frequencies which are different for a plurality of types of alarms are assigned to the plurality of types of alarms. The group units are polled from a central station for each type of the plurality of alarms by means of interrogating signals comprising the signals of the second specified frequencies and the signals of the third specified frequencies, so that when an abnormal condition exists at any of the subscriber locations in the polled group units, the subscriber generates a signal of the first specified frequency assigned thereto to answer to the polling for that type of alarm corresponding to the abnormal condition. The central station discriminates and displays the answering subscriber and type the alarm condition in accordance with the frequency of the answer signal and the second and third specified frequencies generated for the polling at the time when the answer was made.

An FM trap circuit in an amplifier mounted on a roof top antenna is made operable from inside the home by providing a switch on the amplifier which is responsive to the negative half cycle in an A.C. power signal to disable the trap circuit and a switch in the home for selectively sending a full cycle A.C. power signal or a half-wave rectified signal to the amplifier.

Remote control device for an amplifier trap circuit

An alarm system utilizes a bidirectional wired TV system constructed to transmit a TV signal received by a community antenna to a central station and a plurality of subscribers' stations through a bidirectionally transmissible line. Each of the subscribers' stations is provided with an automatic and/or manual alarm signal generator for generating a low frequency alarm signal representing any of emergency conditions and the subscriber's number, a carrier wave generator, and a modulator for modulating a high frequency carrier wave signal generated by the carrier wave generator with the alarm signal from the alarm signal generator. The central station is provided with a demodulator for receiving and demodulating the modulated alarm signal transmitted from any subscriber's station through the bidirectionally transmissible line, an alarm signal identifying device energized by the demodulated alarm signal from the demodulator, a carrier wave generator, and a remodulator for remodulating a different high frequency carrier wave signal generated by the carrier wave generator with the demodulated alarm signal from the demodulator. Any of the subscribers' stations are each further provided with a redemodulator for receiving and redemodulating the remodulated alarm signal transmitted from the central station through the bidirectionally transmissible line, and an alarm signal identifying device energized by the redemodulated alarm signal from the redemodulator.

Alarm system utilizing bidirectional wired television system

In an alarm system utilizing a bidirectional wired television system, a large number of subscribers are combined in a plurality of group units, whereby the subscribers in each group unit are assigned with specified frequencies which are common to the respective group units but are different for the respective subscribers in the group unit, and the respective group units are assigned with another specified frequencies which are different for the respective group units. The group units are sequentially polled by interrogating signals comprising said another specified frequencies and applied from a central station, whereby when any subscriber in the polled group has an abnormal condition at its location, the subscriber answers to the polling by a signal of the specified frequency assigned to it. The central station discriminates and displays the answering subscriber in accordance with the combination of the frequency of the received answer signal and the specified frequency being generated for polling at the time that the answer signal was received.

In a community TV receiving system in which television carrier signals are sent from a common community receiving antenna through a dividing box to respective TV receivers, all connected through coaxial cables, and an alarm system incorporated therein comprising alarm signal generators each having a resistance peculiar thereto connected to the coaxial cables across the core-tube circuit thereof in the vicinity of the respective receivers, and a common alarm receiver operable in response to the peculiar resistances located at a suitable station for indicating the signal generator location without interference to the TV signals.
