In one embodiment, the present invention is an automobile comprising an instrument panel including an instrument panel top surface, the instrument panel top surface including a portion defining a recessed portion, a first flexible solar panel located within the recessed portion, an energy storage unit connected to the first flexible solar panel and receiving electricity from the first flexible solar panel, and an electronic component connected to the energy storage unit.

Abstract: A cover for a garment bag, comprised of a generally rectangular main section of a durable, flexible sheet material with an up turned border. The main section is adapted to be folded in half after the garment bag is placed within the upturned border, the folded together halves of the main section then being zippered together to enclose the bag. Retainer straps are attached to the bag interior and connected across the middle of the garment bag, and an additional handle retaining strap is secured at one end. A zippered opening extends across the midsection of the cover, enabling garment bag handles to be exposed for extended carrying of the covered bag. External and internal cover pockets are also provided for additional storage.

Abstract: In a parallel input signal processor, parallel input signals are processed using logic (selective weight) averaging. A multiple number of signal detectors are placed relatively close together at the location at which signal detection is desired. The polarity of each of the input signals, with respect to a threshold value, is determined. If at least a predetermined number of the input signals have the same polarity with respect to the threshold value, the signals having the same polarities are amplified, combined, and averaged to form an output signal. Those signals not having identical polarities with the least predetermined number of signals are not included in the output signal. In the event that the number of input signals in coincidence with respect to the threshold value are not at least this predetermined number, no output signal is produced. The predetermined number is at least a majority of the input signals.

Abstract: The pulse-width discrimination system receives an input pulse whose leading edge enables an oscillator. The oscillator outputs frequency pulses to a comparison counter which counts the frequency pulses and compares them to a predetermined value, representing a minimum pulse width in which the user is interested. If the predetermined value is reached, the comparison counter triggers a tolerance window network which outputs a pulse, whose width represents the tolerance window, to one input of a coincidence output network. The input pulse is also received by a trailing-edge detector, which outputs a pulse to another input of the coincidence output network upon detection of the input pulse's trailing edge. If the input pulse's trailing edge coincides with the tolerance window, the coincidence output network will output an indication signal. Regardless of coincidence, the trailing edge of the input pulse disenables the oscillator, and the comparison counter is reset by the trailing-edge detector's output pulse.

Abstract: The luminaire raising and lowering system includes a mast head in which a plurality of sets of pulleys are located. A carrier ring containing a number of lighting fixtures is suspended from the top head mast by a plurality of cables associated with respective ones of said sets of pulleys. Those cables are connected to a main winch cable through intermediate linkage means which compensate for differences in the length of said plurality of cables and enable the carrier effectively to "float". Means are also provided to monitor the tension on the main winch cable thereby preventing accidents due to undue slackness of the main winch cable or mispositioning of the same on the winch reel. Four cable and three cable systems are disclosed. Novel latching means are provided to take the load off of the suspension cables when the carrier is at the top of the pole in normal use.

Abstract: An articulated mounting device for mounting an object such as traffic signals, signs or the like on vertical or horizontal poles or masts comprises a central apertured plate for attachment to the bracket holding the traffic signal, a first plurality of substantially identical pivotal links releasably coupled to one another and to one side of the central plate, and a second plurality of substantially identical pivotal links releasably coupled to one another and to the other side of the central plate, and two terminal portions respectively connected to the ends of said first and second pluralities not connected to the central plate for releasably coupling the ends of the device together around the pole or mast.

Abstract: A plurality of cables having respective first ends attached to selected portions of a carrier for lights or the like pass over pulleys in the mast head atop a high pole, their other ends being coupled internally of the pole to a winch which winds the cables to raise and lower the carrier for maintenance purposes from its normal highest position. At the latter position latching members on the carrier engage corresponding latching members on the mast head and the latches normally provide the principal suspending support for the carrier. As a safety measure, the ends of the cables coupled to the carrier are provided with signals visible from the ground indicating when the various latching means have been properly engaged.

Abstract: The assembly comprises a spun metal lower pole terminal portion having a plurality of apertures formed toward its lower edge. The terminal portion is placed over a concrete slab or other appropriate base having a plurality of spaced upstanding bolts protruding therefrom. The apertures are large enough to enable the installer to insert a special clamp through each aperture. The clamp has a bifurcated end portion which straddles one of the bolts whereas its other end portion protrudes somewhat through the aperture and has a portion in a vertical plane which acts to prevent lateral movement of the lower terminal portion. The installer then screws nuts over the bifurcated portion and the increased downward pressure is transmitted to a number of protuberances formed on the lower surface of the clamp which act to crush any small pebbles or solid aggregate appearing on the upper horizontal surface of the concrete slab.

Abstract: A signal mounting assembly comprising first and second rigid, generally J-shaped tubular members each having a generally curved end portion attached to a generally straight portion. The cross-section of the second member is slightly larger than the cross-section of the first member so that the straight portion of the first member can be slid into the corresponding portion of the second member. The second member also has adjustable means for engaging and locking the first member when the two members are assembled together to the desired distance between their respective curved ends. In one form, the curved end portions include a straight terminal part in the form of a truncated cylinder which is joined to a correspondingly angled curved part. In another form, the curved portion includes a generally straight part which is terminated by an elbow attached to it.

Abstract: A hanger fitting usually made of metal includes two spaced, substantially parallel and planar rigid portions joined by at least two transverse portions. The planar portions have a first pair of threaded apertures formed generally perpendicular to the planes adapted to be engaged by a first corresponding pair of set screws for engaging a tongue or other member to which it is to be mounted. The transverse portions include a second pair of threaded apertures disposed generally transverse to the first pair and being adapted to be engaged by a second corresponding pair of set screws. Both pairs of set screws engage the tongue to which the fitting is to be mounted thereby to prevent movement of the fitting with respect to said member in two mutually perpendicular directions. The parallel portions also have a lower part adapted to be coupled to a signal assembly, or the like.
