Abstract: A method of analysis of long record length data using mark duration includes displaying together with a portion of the long record length data each mark that identifies a specified feature of interest together with the mark duration. Associated with the mark may be text identifying the feature of interest, measurement values associated with the duration of the mark, or a combination thereof. Multiple sets of marks may be generated for the long record length data, which sets may be combined to generate new marks with duration. The marks also may be filtered to further refine the marks to be displayed according to user specified criteria. In this way analysis of long record length data representing an acquired signal may be readily automated so a user may move from one interesting event to another without having to pan through the long record length data.

Abstract: A ramp system for efficiently transferring a wheelchair or other vehicle from one vertical end of the ramp to the other. The ramp system generally includes a ramp including a slot, wherein the slot extends through the ramp along a longitudinal length of the ramp between an upper end and a lower end of the ramp, a drive assembly mounted proximate the ramp and a catch tool connected to the drive assembly, wherein the catch tool travels between the upper end and the lower end of the ramp via the drive assembly, wherein the catch tool travels within the slot of the ramp.

Abstract: A system is disclosed for equalizing the distribution of pixel intensities in an image displayed by an oscilloscope. In a primarily software implementation, the maximum pixel intensity (I) present in the rasterized input image, the maximum available display intensity (P) and the desired image resolution (R) are the input variables which permit the calculation of thresholds or bins to which each pixel is assigned. By iteratively performing the analysis of existing pixel intensities and bin thresholds, the number of pixels in each bin may be optimized to form an equalized histogram. Another implementation of the histogram equalization system utilizes software to optimize a hardware-based histogram collector.

Abstract: A swinging gate is operated in one direction between open and closed positions by a winch and cable system driven by an electric motor which may be controlled remotely by radio, the winch and motor being carried on a support arm extending from a gatepost on one side of the gate. The gate is operated in the other direction by a falling weight connected to the gate by a cable extending around a pulley on a second support arm extending from the gatepost. The weight is raised when the gate is moved in the one direction by the winch and cable system and is held in raised position by the winch and cable while the gate remains in one of the open and closed positions. When the gate is to be moved in the other direction, the winch is released and the weight is allowed to fall. In a modification of the invention, the winch and cable system and weight are replaced by a reversible electrically operated linear actuator connected between the gate and a support arm extending from the gatepost.
