Abstract: This disclosure relates to a skating rink that includes a skating area, a wall at least partially surrounding the skating area, and a visible mark extending along a perimeter region of the skating area to indicate to a skater traveling head first toward the wall that the skater should look up and to related methods.

Abstract: The present disclosure relates to a tool and methods of using the tool to physically manipulate one or more filtration components, such as filter packs including stacked filtration discs. The tool may include two arms pivotally coupled to another, and may also have respective gripping portions configured to grasp an appropriate region of a filtration component. The arms may be movable toward and away from one another between grasping and non-grasping positions. When in the grasping position, the gripping portions may engage with a complementary coupling member of the filtration component(s). To separate one filtration component from another, the tool may be manipulated so as to decouple and lift the filtration component from a substrate.

Abstract: A grid system is provided that is particularly suited for the suspended ceiling system that varies in the vertical plane. An elongated carrier tube is provided the spans substantially the width of the grid system that has a slot therein adapted to receive the strengthening bulb of a main runner. A clip is provided that seats on the carrier tube that has opposed faces for capturing the bulb of the runner, so as to secure the runner to the tube carrier.

Abstract: An automatically adjustable fifth wheel assembly for a vehicle and trailer combination that adjusts the position of the trailer relative to the vehicle is provided.

Abstract: A flexible ceiling panel is preferably formed from sheet metal, such as aluminum sheet. Each ceiling panel has a generally rectangular shape (corresponding in width to the spacing between the main runners) and is formed with a hem on all four edges. A series of bendable tabs are formed integrally with the hem of the panel. To secure the panel to the associated grid system, the tabs are folded upwardly and outwardly from the panel along two axes to secure the panel to the grid system. Alternatively, a plurality of separate spring clips is used to secure the panel to the grid system. Each clip includes a first leg adapted to have at least a portion thereof received in the hem of the ceiling panel. A second leg extends generally perpendicularly from the first leg and includes a detent extending toward the first leg, the detent being adapted to secure the clip to the flange of the runner.

Abstract: An internal combustion engine cover includes a peripheral rail for attaching a cover to an engine component and an enclosure portion formed integrally with a peripheral rail. At least one port formed in the enclosure portion holds an electronic module which is mounted through the port and which may include an oil separator as well as an electronic device.

Abstract: A motor speed resolution enhancement method and system. A display system controller (202) measures the frame rate of an incoming signal to determine the desired color wheel speed. A digital speed control word (212) representing the desired color wheel speed is written to the motor control circuit (204). The motor control circuit uses the digital speed control word (212) to generate analog control voltages (214) that drive the motor (206). The motor controller (204) also detects the position of the motor and generates a series of commutation interrupts (216). The display system controller 202 accurately measures the input signal's frame rate to determine the proper rate at which to spin the color wheel. The resulting desired speed word has a higher resolution than the motor control circuit (204) is able to receive. The disclosed invention provides a method of increasing the resolution of the digital speed control word (212) without upgrading the resolution of the motor control circuit (204).

Abstract: A method and apparatus for controlling a lamp. A timer (106) reads a rated safe life value from a memory (102) associated with a lamp in a lamp module (104). The memory (102) in the lamp module (104) contains a series of locations in which the rated safe life of the lamp has been stored, and a series of locations for storing the elapsed on time of the lamp. The timer controller (106) reads the series of locations storing the rated safe life of the lamp and verifies the validity of the values using a series of checksums and comparisons between the various values. The timer controller (106) also reads the series of locations storing the elapsed on time for the lamp and verifies the elapsed on time in a similar manner. If either the rated safe on time or the elapsed on time cannot be verified, the lamp is disabled. If both can be verified, and the lamp is enabled until the elapsed on time equals or exceeds the rated safe life.
