Abstract: A touch panel (4) and an operation part (30) are provided on display means (2). A permanent magnet (52) is mounted on a push button (32), and a magnetic metal plate (58) is mounted on a support frame (36). When the push button (32) starts to be pushed down toward the touch panel (4), the push button (32) moves toward the touch panel (4) against magnetic attractive force of the permanent magnet (52) and the magnetic metal plate (58), and an operation forward end part (46) operates a touch switch (4a). Stroke feeling results from this movement. Further, the aforementioned magnetic attractive force abruptly reduces in an initial period of this movement, and an operator of the push button (32) can attain click feeling. Since the stroke feeling and the click feeling are caused in the operation of the push button (32), operability is improved while making the best use of such an advantage that the touch panel (4) is of a thin type.

Abstract: In an arrangement of a vehicle auxiliary heater with an integrated regulating device in the region of the floor in the vehicle cab and a control unit remote from the auxiliary heater, e.g. in the region of the dashboard or on an inner wall of the vehicle, it is proposed that the control unit be operationally connected to the regulation device wirelessly via a bidirectional radio link in which use is made of an r.f. unit with a first r.f. module on the operating side with a transmission and reception section and a second r.f. module on the control device side with a second transmission and a reception section. This obviates the need for the complicated laying of prior art wired connections between the control unit and the regulating device of the auxiliary vehicle heater, making the heater particularly suitable for subsequent fitting in commercial vehicles.

Abstract: A security system having a two way wireless keypad which operates in a particular manner for improved operation. The keypad processes information to effectively reduce communications between the control panel and the keypad. The keypad selectively activates and deactivates a transmitter and receiver arrangement for power conservation reasons. The system provides confirmation of communications between the keypad and the control panel to increase the reliability of the system.

Abstract: A remote control system comprising a remote commander and an electronic device main unit, in which the remote commander transmits a command signal to the electronic device main unit, the electronic device main unit receives the command signal, and the electronic device main unit transmits a signal that represents a setting state of the electronic device main unit. The remote commander receives the signal from the main unit and the remote commander displays the setting state of the electronic device main unit so that it can be checked by the user.

Abstract: A channel selector used in a television set, video cassette recorder and the like includes a key pad having tens key corresponding to the decimal numbers zero through nine. A microcomputer is also included therein, which is operated in response to the key pad output and controls on screen display circuit, a tuning voltage generator. A desired channel number is easily selected by the microcomputer which is operated by the program therein. As a result, a user may operate easily and quickly the channel selector without feeling a tedium due to a delay time between the activation of a first key and the activation of a second key.

Abstract: A system provides for transmission of information between an article carrying information and an apparatus for processing the information, in which the article includes an arrangement for modulating the reflectance of at least one area of a liquid crystal device as a function of information to be transmitted to the processing apparatus. The system includes a reader having a station for receiving the article, and an optical arrangement at the station which is sensitive to the reflectance of the area of the liquid crystal device to form signals representative of information given out by the article. Also included is an arrangement for the transmission of these signals to the processing apparatus.

Abstract: A delay means in a security apparatus for identifying a code of characters to authenticate access to the apparatus by matching an entered code with a stored value by a procedure which so enciphers the coded information as it is entered into the apparatus and displayed on a keyboard that disclosure of the code by observation of the entry operation is prevented. A delay timing circuit produces a delayed signal in the matching of the entered code and the stored value so that the length of the period of time for authentication is controllable.

Abstract: Observers in the theater of operations use remote units to encode and transmit messages characterizing multiple events observed in theater of operations. The messages are composed from a predefined set of symbolic ideograms, representing and describing actions or objects likely to occur in the theater of operations. A central control center receives the multiple incoming transmissions. The messages are decoded and processed to produce a holistic accumulation of the various observations. According to one embodiment, the accumulation might graphically recompose theater activity according to correlated data received from the observers.

Abstract: According to the invention, the keyboard consists of a matrix of keys and variable visible indicia. Each of the variable visible indicia is associated with a key. Upon each keystroke on the keyboard, the system randomly changes the positions of all of the indicia on the matrix. Because the true value of any particular key is independent of the value displayed on the variable visible indicia, a casual observer can not learn the keystrokes being entered into the keyboard. If the code entered at the keyboard matches a stored value, the user is granted access.

Abstract: A method for compressing formatted code is disclosed. According to the method, the code is scanned so that all different burst and pause lengths of the code are found. The lengths are then arranged as elements of an array, with each element having a representative element number. Then, the formatted code is scanned for all possible burst-pause length couples found together. Using the "couple" information as well as the element numbers of the first array, a second array is provided with each element having two nibbles. Both nibbles of the second array element are used to point to an element number of the first array. Finally, a third array which represents the compressed formatted code is generated. The third array is also formed with elements having two nibbles. However, the nibbles of the third array point to the second array element numbers and can properly represent the entire formatted code therewith.

Abstract: An electronically controlled oven comprises a main body and a remote controller which is separate from said main body. The remote controller includes a scanner for scanning a code representing a recipe and outputting a code signal indicative of the selected recipe, a computer for judging whether this code signal should be transmitted to the main body or not, and a transmitter for transmitting code signals in a wireless form such as by infrared radiation.
