Abstract: A system to augment the collected odometer data points with more precise location data which provides an indication of a location of a vehicle associated with the odometer at a given time, such as Global Positioning System (GPS) GPS data points. Additionally, the GPS data points may be collected at a higher sampling rate than the odometer data points, thus providing a more precise indication of a distance traveled by a vehicle at any given time.

Abstract: Systems and methods of controlling the output of an LED light fixture. The LED light fixture includes a plurality of light sources and a controller. The controller is configured to receive a first set of input data and determine a difference between the first set of input data and a second set of data stored in memory. The controller is also configured to set a slew time based on the determined difference and control the output of the light fixture based on the slew time. The slew time is inversely related to the determined difference between the first set of input data and the second set of data, and the slew time corresponds to the amount of time that the output of the light fixture is to take to transition from a present output of the light fixture to a new output of the light fixture.

Abstract: Systems and methods for controlling the spectral content of the output of a light fixture. The method of one embodiment includes driving the output of a light fixture to a target color and controlling the spectral content of the output of the light fixture. For example, a desired color is inputted using a color control methodology. A set of light source output intensity values that produce the desired color are identified, and then the light sources are driven to the identified output intensity values. A user is able to control the spectral content of the output of the light fixture by modifying the output intensity value of one or more of the light sources. After modifying the output intensity values, the color control and matching technique is used to identify a new set of output intensity values that maintain the previous target color but incorporate the changes in spectral content.

Abstract: Systems and methods for controlling an output of a luminaire. The luminaire uses stored spectral information for light sources within the luminaire to determine a coordinate for each light source within a color space. A desired output color is also converted to a coordinate within the color space. The distance between the desired output color coordinate and each of the coordinates corresponding to the light sources is calculated to select initial control values for the light sources. The initial control values for each light source are individually modified by a step size value, the total output of the luminaire is calculated and converted to a coordinate within the color space, and the distance between the total luminaire output coordinate and the desired color coordinate is calculated. The control values for the light sources are iteratively modified until the luminaire output coordinate is within a threshold value of the desired color output.

Abstract: Systems and methods for controlling an output of a light fixture. A light fixture of one construction includes four or more light sources and is configured to produce an output that mimics the color temperature changes of an ideal black-body radiator based on one or more input parameters. The input parameters correspond to, for example, a desired target color and an intensity for the desired target color. A white point setting is determined based on the one or more input parameters and a relationship between the one or more input parameters and the color temperature of an ideal black-body radiator. A color temperature transform is selected based on the white point color temperature setting, and is used to determine a color coordinate corresponding to a modified target color. A set of light source output values corresponding to the modified target color are identified, and the light sources are driven to the identified output values.

Abstract: Ladder Tool & Equipment Hook is a hook made of a single piece of steel or steel alloy which can be hung on the rung of a ladder to hold tools, equipment, pails, or tool pouches weighing up to 20 pounds. This hook is designed to allow a workman to hang a saw, nail gun, or paint gun on the hook by use of the handle grip. It is further designed to allow the ladder it is hanging on to be moved gently without unloading the hook.

Abstract: A bracket assembly for supporting one or more curtain strips includes an elongated rod; a first bracket having a slot therein for supporting one end of the rod; a second bracket having means therein for supporting an opposite end of the rod. The first bracket has at least two fastener holes therein, and the rod has a through hole at one end thereof perpendicular to an axis of the rod. The through hole is alignable with one of the fastener holes so that a fastener may extend through the through hole and one of the fastener holes to thereby lock the rod to the one bracket.

Abstract: Linked game controllers coupled to a single input port of a computer game are configured such that all controllers may be active at the same time. One controller is coupled to an input port on the computer game which has both a parallel-bit interface and a bit-serial interface. This controller provides information on its own control function via the parallel interface and information derived from each of the linked controllers via the serial interface. Each of the controllers includes a flag bit, in the provided information, that indicates whether the controller is the last controller in the sequence of linked controllers. The computer game stores data values provided by the parallel interface and then shifts values provided by the serial interface into an internal register until one of the flag bits, indicating the last controller in the sequence, has been shifted. The shifted data is then separated into different control functions which are then provided to the computer game apparatus.
