Title: Assimilating utility meter data with electronic probing
IPC: H04M11/06
Filed: 1981-08-21
Abstract: Utility meter data is assimilated at the meter locations by accumulating customer profile information for a plurality of meter customers on a base computer, transmitting said customer profile information over a telephone line to a telephone receiver, and coupling the telephone receiver to a portable computer for imposing the customer profile information into it. The portable computer is then disconnected from the telephone receiver and carried to the site of a given meter to be read. The new meter reading is imposed into the portable computer by temporarily coupling the portable computer to the meter being read and electronically transmitting the data of the meter to the portable computer which calculates the charge for utility usage and prints a bill for the meter customer at the site of the meter. The updated customer profile information is imposed on a storage means of the portable computer for later transmission to the base computer by coupling the portable computer to a telephone transmitter of the manually held type. <IMAGE>

Patent GB-813635-A (GB)
Abstract: 813,635. Calculating-apparatus. MINISTER OF SUPPLY. March 6, 1957 [Dec. 13, 1955], No. 35724/55. Class 106 (1). A calculating machine has a rotary actuator comprising, for each order, a set of toothed segments arranged so as to be movable selectively from inner ineffective positions to outer positions in which they are effective to drive an associated totalizer wheel. Each order has four toothed segments 40 which are carried by arms 37 pivoted to a disc 35 fast on an operating shaft 31 rotatable by means of a crank handle. One disc 35 may carry the segments of two orders. Feet 41 of the toothed segments bear on a cam 43 rotatable relative to the shaft 31 by means of a setting lever 52 movable in a spring gate 53. The segments have four teeth, two teeth, two teeth, and one tooth respectively and by means of a cam 43 they are raised in various combinations to bring a number of teeth corresponding to the digit set into effective position. On rotation of the operating shaft 31, these teeth drive a corresponding totalizer wheel 47 through an intermediate wheel 46 carried by a bracket 48 and engaged by a detent 51. The machine may be adapted for handling Sterling amounts or for multiplication. Transfer mechanism.-At transfer a tooth on one side of the totalizer wheel 47 advances the intermediate wheel 46 of the next higher order by one step. The toothed segments of the several orders are staggered so that the entries of transfer units take place at different times from direct entries. Zeroizing.-The shaft 49, Fig. 6, of the totalizer wheels is displaced axially against a spring and then rotated to zeroize the wheels, which are held against axial movement by distance pieces 50a, by the co-operation of lugs 60 on the shaft and lugs 59 projecting inwardly from the wheels. Resetting setting levers.-The levers 52 may be restored to zero position by rocking arms 61b carrying a rod 61a by means of a lever 62. The rod 61a is normally held out of the path of the levers 52 by guides 65, but is moved inwardly by springs 64 to engage them when the arms 61b are rooked upwardly.

Title: Demodulator for encoded RF signals
Inventor: WAINWRIGHT R C
IPC: G02F1/125
Filed: 1982-01-09
Abstract: A demodulator for decoding encoded RF signals comprises a coherent light source such as a laser diode (10) a collimating lens (12) a transducer (16) which produces a transversely extending surface acoustic wave which interacts with the collimated optical wave from the lens (12). One of the waves is modulated by the incoming signal and the other wave is modulated by a reference signal. A second lens (18) focuses the undiffracted light which is blocked by a stop (20) and diffracted light passing through the lens (18) falls on an array of photodetectors (22). An output signal is obtained by scanning the array of photodetectors (22). A further lens may be employed to focus the diffracted light to form a magnified image onto the photodetector array so as to allow the latter to be positioned remote from the stop (20) and thereby improve the signal to noise ratio of the device. <IMAGE>
