Abstract: In an example embodiment, a method may generate an item layout map for a shelving unit, where the shelving unit stores item types associated with a product category. The method may determine product attributes associated with the product category and divider configurations of the shelving unit, where a divider configuration divides the shelving unit into one or more candidate regions. The method may generate an ontology entry associated with a product attribute and the divider configuration based on the item layout map and the divider configuration of the shelving unit, the ontology entry indicating a regional entropy values of a product attribute for the candidate regions generated by the divider configuration. In some instances, the method may generate a guidance instruction related to the product attribute of the product category based on the ontology entry and provide the guidance instruction to a user.

Abstract: A ruggedized housing for a portable radio is provided. The housing is formed of a front housing portion, a rear housing portion, and a battery cover. The front housing portion has a top surface with offset tapered edges, without any user interface radio controls. An antenna protective cover having offset tapered edges and a straight vertical side couples to the top surface. The offset tapered edges of the antenna protective cover align with the offset tapered edges of the top surface of the radio. The straight vertical side of the antenna protective cover aligns flush with the side housing of the radio. A lanyard through-hole feature is located and protected by a contoured end of the top surface and is located diagonally opposite a top tip end of the antenna protective cover. The top tip end of the antenna protective cover and the lanyard encasement are sloped in opposite directions.

Abstract: The present subject matter is directed to an adaptive load circuit for use with traffic light control systems so as to permit operation using low current consumption lamps where the traffic light control systems were originally manufactured for operation with higher current consuming lamps. The adaptive load circuit provides a mechanism whereby an existing traffic light control system is fooled into accepting use of a low current consuming lamp by creating a specifically timed signal during an interval that the traffic light control system normally checks to determined lamp load characteristics.

Abstract: A method for varying gain exponentially with respect to a control signal is provided. The method includes receiving a primary control signal. A secondary control signal is generated based on the primary control signal. The secondary control signal is provided to a variable gain amplifier and is operable to exponentially vary a gain for the variable gain amplifier with respect to the primary control signal.

Abstract: A method for generating a temperature-compensated control signal is provided. The method includes receiving a constant control signal. A temperature-compensated control signal is generated based on the constant control signal. The temperature-compensated control signal is provided to a variable gain amplifier. The temperature-compensated control signal is operable to cause the variable gain amplifier to function independently of temperature.

Abstract: A high-speed phase-frequency detection module is described to function at very high frequencies and to produce very low jitter. In one embodiment, high-speed phase-frequency detection module includes a PFD with edge-triggered asynchronous-reset true-single-phase-clocking (“TSPC”) D flip-flops that have very short CLK to Q and Reset to Q time delays. In one embodiment, the high-speed phase-frequency detection module includes a charge pump, without replica or feedback, that can respond to the very narrow pulses from the PFD and produce output voltages with small ripple, thus leading to low VCO output jitter.

Abstract: Tuning of a filter circuit is accomplished by determining a real RC time constant value for the filter circuit, then comparing the real RC vale to a predetermined RC value. If the real RC value does not match the predetermined RC value, the real RC value is varied (e.g.

Abstract: An adjustable RF microwave tuning post for use in an RF cavity is disclosed. It is comprised of a flexible integrally-formed hollow tuning post disposed in the RF cavity. A drive shaft extending internally of the tuning post is provided to vary the dimensions of the tuning post. The drive shaft is connected to the tuning post at the top end thereof and connected at the other end of the drive shaft to an adjusting nut. The tuning post is made flexible by the use of bellows, which in a preferred embodiment of the invention is located along the side walls thereof.
