Abstract: A control device for an automobile has at least one sensor (8) for detecting an operational state of the automobile. An output from the sensor is applied to a sample and hold circuit (11) which is adapted to provide a time displaced output to a hierarchical group of neural elements (13). The neural elements operate upon said time displaced signals by varying the weighting of the signals and/or threshold values of the neural elements in accordance with a desired output parameter. The output of the neural computer is applied to a control circuit (2) which is adapted to control an automobile actuator. The hierarchical group of neural elements are provided with numerous forms of different learning functions so that the desired output parameter is achieved. In one such embodiment (Figure 32) desired parameters are applied to said neural computer and to a comparator, signals derived from sensors associated with automobile actuators are also applied to said comparator whereby difference signals are outputted from said comparator to control the weighting and/or threshold levels of the neural elements. The invention may be applied to different functions such as controlling air/fuel ratio, ignition timing, knock control, O₂ sensing, suspension adjustment, and road surface detection.

Abstract: In an apparatus and method for removing cigarettes from cigarette packs to facilitate individual cigarette recovery and tobacco reclamation, individual packs of cigarettes are conveyed to an opener stage (102) which removes both end panels of a cigarette pack, and then to an extraction stage (104) which increases the cross-sectional area of the pack, thereby loosening the packed cigarette matrix, applies a nonintrusive removal force, removing the cigarettes from the pack and separating the empty pack from the removed cigarettes. The cigarettes are transported to further processing which may include repacking of intact and otherwise acceptable individual cigarettes or, alternatively, separation of the tobacco from the filter and paper of the cigarettes.

Abstract: A downhole cementing tool (10) includes a tubular housing (12) having an inner passage (18) defined longitudinally therethrough and having a radially outer surface (20). The housing also has a cementing port (22) and a longitudinal slot (26,28) both disposed through a wall thereof. An outer closure sleeve (30) is slidably received about the outer surface of the housing and is movable relative to the housing between an open position wherein the cementing port is uncovered by the closure sleeve, and a closed position wherein the cementing port is closed by the closure sleeve. An inner operating sleeve (32) is slidably received in the housing and slidable between first and second positions relative to the housing. à pin (36,38) extends radially through the slot and fixedly connects the operating sleeve and the closure sleeve together for common longitudinal movement relative to the housing. When cementing is completed, a cementing plug engages the operating sleeve and causes it to move the external closure sleeve downward thus closing the cementing port. Internal components of the cementing tool may then be drilled out of the housing thus leaving a smooth bore through the cementing tool through which other equipment can be run.

Abstract: A charger 11 is configured to receive alternatively for charging, one at a time, battery packs having three different shapes, namely, a large oval pack 213 (FIG. 10), a small oval pack 219 (FIG. 11) and a D-shaped pack 225 (FIG. 12). When pack 219 is inserted into receptacle 25, a pack locator 77 biases pack 219 against the receptacle sidewall 29 and into a location to properly mate with electrical contacts 65, 66. When pack 225 is inserted into receptacle 25, locator 77 biases pack 225 against a retractable abutment 85 spaced from locator 77 and into a proper location to mate with contacts 65, 66. When pack 213 is inserted into receptacle 25, receptacle contacts 47, 49 mate with pack terminals 214. When pack 213 is in receptacle 25, contacts 65, 66, pack locator 77 and abutment 85 serve no function and are substantially retracted from receptacle 25 by engagement with pack sidewall 216. Thus, charger 11 is automatically adaptability for charging a plurality of battery pack designs in a simple and low cost manner.

Abstract: In a digital radio receiver, an amplitude limiter circuit (20, 21) is included for producing a constant-amplitude IF signal from a received digitally modulated IF signal. An orthogonal detector (22) orthogonally mires the constant-amplitude signal with a reference carrier and produces an in-phase baseband signal (I) and a quadrature-phase baseband signal (Q). The baseband signals are converted (24, 25) to first and second digital signals, and supplied to respective multipliers (26, 27). A logarithmic detector circuit (30) is coupled to the amplitude limiter (20) for generating a signal representative of the amplitude of the received IF signal. The logarithmic scale of the amplitude signal is converted to a linear scale by a logarithmic-to-linear converter circuit (32, 33) and the resultant supplied to the multipliers (26, 27) in which it is multiplied with the digital baseband signals. The outputs of the multipliers are coupled to an equalizer (28) for eliminating bit errors, such as a maximum likelihood sequence estimation (MLSE) equaliser. The amplitude limiter may comprise a series of tapped limiter amplifiers, and the logarithmic detector circuit may comprise a corresponding plurality of detectors, coupled to the tap points of the series of amplifiers, and an adder (Fig.3).

Abstract: To obtain multiple use from a common two-core physical line, there are several transmission links with useful and signalling channels. At one end, there are interface devices (SV) at the exchange end and at the other end there are interface devices (SA) at the subscriber end. Each interface device has its own control device (ST1) and, respectively, (ST2) which exchange messages with one another via a signalling channel. To test such a device, a particular signal is applied at the exchange end, by means of which the entire transmission link is brought into the test state. Different signals, which are applied at the exchange end, make it possible to trigger different test and monitoring processes, the results of which are transmitted by corresponding signals to the test equipment connected at the exchange end. Apart from testing the individual devices for operability, a continuity check with tone signals is also possible. <IMAGE>
