Abstract: A pool skimmer opening cover system for prevention of intrusion of debris and liquids into the pool filtration system during installation of the pool. The system has at least a first cover and a second cover designed to be installed on the above-ground circular opening of a pool skimmer and the subterranean pool facia rectangular opening. Each cover may be installed into the corresponding location subsequent to pool skimmer installation but prior to the completion of pool construction to prevent the intrusion of debris and liquids into the systems thereof. Each cover may be removed subsequent to installation and construction of the pool to enable use of the skimmer upon such completion. A third cover to be used upon construction completion prior to filling the pool and methods of use and/or installation.

Abstract: An off-duty scheduling system for police officers automatically generates a list of qualified available officers. Filtering eliminates, from the candidate pool, officers lacking requisite training or credentials, officers who have reached or exceeded off-duty work limits, and inactive officers. Multi-level sorting arranges the candidate pool in order of priority based upon specified criteria, such as, time from last off-duty assignment and seniority. Officers are invited to perform the job, until the job is fully staffed. Start and end of job performance are tracked and reported, with payments made automatically upon completion.

Abstract: Systems, methods, apparatuses and computer-readable media for receiving data associated with a plurality of users, such as a group of employees receiving benefits from an employer. The plurality of users may have a primary insurance provider. Insurance information associated with one or more covered services or claims submitted may be received from the primary insurance provider and matched to the plurality of users to identify a portion (or any) of the users who have submitted a claim or received covered services. In some arrangements, a determination may be made as to whether the identified users have supplemental coverage. If so, a notification may be transmitted to the user indicating eligibility for coverage.

Abstract: A dust filtration unit for a frac sand storage bin and a method for using the same is disclosed. The dust filtration unit includes an adapter base adapted for attachment to an opened inspection hatch on the sand storage bin, a diffuser manifold attached to the adapter base, and a top plate of the diffuser manifold defining a plurality of filter bag orifices. Each of a plurality of filter bags is releasably attached to one of the plurality of filter bag orifices. In a non-limiting embodiment, the dust filtration unit further includes a hinge between the adapter base and the diffuser manifold, wherein the hinge rotatably attaches the adapter base to the diffuser manifold.

Abstract: The invention relates to an electrical cable (1, 10) comprising at least two conducting strands (2, 3) and theft deterrence means in the form of a marking (8). The main characteristic of an electrical cable (1, 10) according to the invention is that the marking consists of a series of relief prints (8) akin to a bar code.

Abstract: A device for detachably affixing a piece of luggage to a person includes a belt plate that can be affixed to a belt and a shaft that is movably affixed to the belt plate and that has a threaded portion that accommodates a nut. A clamp that includes a bottom clamp element and a top clamp element may secures attach a handle of a piece of luggage to the device, ensuring ease of movement and hands-free operation. The bottom clamp element may be rigidly affixed to the bottom of the shaft or may be adjustable by use of a second nut that may support the bottom clamp element in a particular position. A top clamp element may be configured about the shaft and linearly movable about the shaft, held in place by the first nut to secure a luggage handle in the area between the top clamp element and the bottom clamp element.

Abstract: A rebar processing station taking the form of an hydraulically powered rebar cutting, bending, and shaping table is disclosed. A rebar cutting assembly comprises a pair of slotted, hardened plates or dies that cooperatively function to shear a rebar. A rebar grasping, bending, and shaping assembly comprises rebar grasping and clamping means, a shaping plate or die, and a movable former, such as a roller. For convenient transport, the table may be provided with appropriate features allowing cooperative engagement with appropriate attachments and/or implements associated with on-site construction equipment.

Abstract: Apparatuses, systems and methods for transmitting and receiving modulated impulse radio signals. An impulse radio receiver includes a time base, a precision timing generator, a template generator, a delay, first and second correlators, a data detector and a time base adjustor. The time base produces a periodic timing signal that is used by the precision timing generator to produce a timing trigger signal. The template generator uses the timing trigger signal to produce a template signal. A delay receives the template signal and outputs a delayed template signal. When an impulse radio signal is received, the first correlator correlates the received impulse radio signal with the template signal to produce a first correlator output signal, and the second correlator correlates the received impulse radio signal with the delayed template signal to produce a second correlator output signal. The data detector produces a data signal based on at least the first correlator output signal.

Abstract: A bi-phase modulator for Ultra Wideband (UWB) waveforms uses a symmetrical transformation device and a selector device to produce bi-phase modulated UWB waveforms in response to an information signal. The symmetrical transformation device receives an input UWB waveform and produces equal but opposite polarity output waveforms. The selector device determines whether an inverted or non-inverted UWB waveform is output in response to the information signal.

Abstract: Apparatus for producing a light mask for balancing light across a display area of a vehicle instrument cluster comprises a camera, a digitiser and a computer. An image of the display area is obtained and digitized to produce data relating to the illumination levels of the image at a plurality of pixels. The illumination levels are used to calculate an appropriate light mask for the display area on the basis of the transmissive density of the masking ink used and or a reference illumination value relating to the least lit part of the display area which it is desired to illuminate. The light mask comprises an array of dots having a diameter related to the amount of attenuation required in the area in which the dot is located. Up to three masking layers may be provided if a single layer is insufficient to produce the required attenuation with the chosen masking ink. Balanced coverlays can readily be produced, and the number of masking layers required can also be reduced.
