Abstract: In a sense amplifier circuit, an output potential is set in a data output state when an operation of the sense amplifier (SA) is a worst pass before the start of read access. In a memory read mode, when data corre­sponding to the worst-pass operation of the sense amplifier circuit is read out, the circuit is previously set in a corresponding data output state. A time delay (gate delay) by a gate does not occur. In contrast, when data corresponding to the best-pass operation of the sense amplifier circuit is read out, the gate delay occurs by this operation. The gate delay, however, is shorter than that of the worst pass. As a result, only the best pass is present as the operation mode of the sense amplifier circuit. Therefore, a high operation speed is achieved, so that a high read speed of the entire memory is achieved.

Abstract: A trip interlock assembly 20 trips a circuit breaker 32 any time the circuit breaker is removed from its panel mounting. The trip assembly is adapted to be disposed about a load side terminal 24 and cooperate with the circuit breaker tripping apparatus. In one embodiment, the trip assembly includes a housing 50 and a spring-loaded actuation arm 48, disposed generally perpendicular to the circuit panel surface. The actuation arm is formed with a cam surface 100 which cooperates with a trip pin 106 adapted to actuate said circuit breaker tripping means. The trip pin acts as a cam follower and rides along the cam surface formed in the actuation arm. When the actuation arm is in an inward position the trip pin is in a normal position. However, when the circuit breaker is removed from the panel, the actuation arm under the influence of a biasing spring 78 moves outwardly. This causes the cam surface on the actuation arm to actuate the trip pin to trip the circuit breaker. In an alternative embodiment 220 of the invention, the trip interlock assembly includes a bell crank 226 with a reciprocally mounted plunger 228 which actuates an armature in the tripping means directly, instead of by way of the trip pin, anytime the circuit breaker is removed from its panel housing.

Abstract: A radio alarm system is described which offers adequate protection against interference due to blocking of the radio paths and against external manipulation. For this purpose, it is proposed that each signalling unit of the alarm system transmits at least two radio signals for an alarm signal, using a different carrier frequency and being coded in identical or different fashion. The central unit accordingly receives with its receivers the at least two radio signals from each signalling unit and checks the affiliation of the signalling units transmitting the radio signals by checking the validity of the coding. It is proposed in addition that an evaluation unit be provided in the receiver unit of the central unit which identifies the field strength of each received radio signal, analyses the associated data telegrams for affiliation to the system of the signalling units transmitting them, if an invalid data telegram is detected, compares the value of the received field strength of the radio signal concerned with a predefinable minimum value and, if this minimum value is exceeded by a predefinable amount, where this amount must be exceeded for a specific time period, triggers a warning indicator. <IMAGE>

Abstract: A lockable sleeve drainage catheter is disclosed for percutaneous insertion into a patient and drainage of fluid therefrom. The drainage catheter includes a flexible distal end that is preformed for retaining the distal end of the catheter that is inserted in the patient. For insertion, the distal end is straightened with the use of a stiffening cannula that is inserted through the hollow passageway of the catheter. When the catheter is inserted in the patient, the stiffening cannula is removed, and a flexible tension member positioned within the passageway of the catheter is drawn to position the distal end in the desired retention configuration. A lockable sleeve positioned at the proximal end of the catheter draws the flexible tension member through the passageway of the elongated member tube to position the distal end in the retention configuration. The catheter also includes a locking collar at the proximal end of the elongated member tube having an annular recess formed therein. The distal end of the lockable sleeve includes an annular step for engaging the recess of the collar and locking the sleeve in a fixed position relative to the elongated member tube of the catheter. When fully extended and locked, the sleeve and elongated member form a fluid tight interconnection. A Luer lock connector is affixed to the proximal end of the sleeve for connection to a drainage collection system.

Abstract: In order to eliminate the need for spread-spectrum code synchronization, a code divided into a suitable number of digits is applied to a transmitter and a receiver. The transmitter multiplies an original signal by each subdivision of the code to produce n-number of new baseband signals. Carrier waves having n-types of frequencies are modulated by these signals and the modulated signals are added to obtain an ultra-wide band signal, which is then transmitted to the receiver. The receiver separates the received signal into the narrow band components which prevailed prior to the adding operation in the transmitter, and then demodulates each component into a baseband signal. Each of these demodulated signals is multiplied by a code the same as that on the transmitting side, whereby n-number of original signals are obtained. Original signals obtained from a signal spread by a code different from that of the receiver are not n in number. Thus, spread-spectrum communication can be realized without requiring spread-spectrum code synchronization.

Abstract: The slide switch has a base body (1) with contact elements (2, 3) which are embedded in pairs and, on the top, form in each case a fixed contact (4) and a sprung contact arm (5). A slide (6) having a U-shaped cross-section covers the contact arm and the complete base body by means of lateral guide arms (6b) and is supported by means of a sliding guide in the longitudinal direction of the contact arm such that it can be displaced on lateral guide ribs of the base body. When the contact is open, the contact arm is largely free of tension, while it is pressed against the fixed contact (4) by means of a switching cam (10) and a bend (11) for closing the contact. In consequence, the contact elements and the base body are largely free of tension when the contact is open, as a result of which deformation is prevented in the event of high temperature stress during surface mounting. In addition, the slide is easily accessible for manual operation even if the switch has very small dimensions, and the switching state can easily be identified by the position of the slide. <IMAGE>
