Abstract: A medical bed frame may include a base frame, a pair of side members selectively movable laterally towards or away from the base frame, a first and second drive assembly each comprising: a first and second pair of cams configured to move the pair of side members, and a central linkage for rotating the first and second pair of cams, a first actuator operatively connected to the central linkage of the first drive assembly and the base frame, and a second actuator operatively connected to the central linkage of the second drive assembly and the base frame, wherein the first and second actuator are configured to selectively move the central linkage in one of a first direction and a second direction, whereby selective movement of the first actuator and the second actuator results in lateral movement of the pair of side members towards or away from the base frame.

Abstract: The resolver input module for use in programmable controller systems is one of several modules mounted in a rack to form a programmable controller. The module's function is to provide position data from an externally located resolver which is connected to a machine's shaft to the programmable controller's processor module. This is accomplished by moving the resolver analog-to-digital conversion circuitry from an external module location to the programmable controller input/output rack and coupling this circuitry to circuits which synchronize the programmable controller's input fetch signals. Additionally, a user operable entry mechanism for digitally offsetting the resolver position by a user-selectable amount while accommodating different scale factors is provided. Synchronization and alignment circuitry are provided for synchronizing and aligning data to compensate for different resolver gear ratios in coarse-fine geared resolver decoding circuitry.

Abstract: The programmable control device is arranged to accept numerical data information from a transducer associated with a particular machine. Selected outputs are stored in addressable tables, including an I/O address table, relative to outputs which are of special interest in a program and which are to be supplied to output devices. The programmable control device, utilizing a micro-computer, responds at high speed to the numerical data and status information from the input devices, selects or calculates the appropriate output, generates visual displays, and periodically couples the addressable tables to the output devices.The control device only requires a scan time of approximately 100 to 500 microseconds and acheives the high speed by processing input data, storing selected output data in addressable tables, and periodically coupling the addressable tables to the output devices.

Abstract: The programmable control apparatus includes an absolute position transducer capable of being mechanically coupled to a machine and electrical circuitry for generating signals indicative of and related to the machine position, a programming unit including a microcomputer, visual display device, program input circuitry, one or more programmable memory position output devices (PMPODs) each of which includes a non-volatile memory, latching circuitry and output interface circuitry, and terminal blocks for interconnection of the absolute position transducer to the programming unit or the PMPOD.
