Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a surfel map to generate long range localization. One of the methods includes obtaining, for a particular location of a vehicle having a camera and a detection sensor, surfel data including a plurality of surfels. Each surfel in the surfel data has a respective location and corresponds to a different respective detected surface in an environment. Image data captured by the camera is obtained. It is determined that a region of interest for detecting objects for a vehicle planning process is outside a detectable region for the detection sensor. In response, it is determined that the image data for the region of interest matches surfel color data for the surfels corresponding to the region of interest. In response, the vehicle planning process is performed with the region of interest designated as having no unexpected objects.

Abstract: In order to improve performance and responsiveness for drag-and-drop actions for Web applications, the amount of JavaScript loaded and executed at each increment of the mouse as it moves during a drag-and-drop action should be minimized. This can be achieved by harnessing the efficient and native-code algorithms built into Web browsers. Instead of using a JavaScript algorithm to compute which drop target the mouse is on, an overlay with placeholders can be placed on top of the page using z-index, where the placeholders are placed directly on top of the drop targets. The current drop target can be computed using the browser's built-in onmouseover and onmouseout events on the placeholder elements, thus freeing the browser from loading and executing too much JavaScript.

Abstract: A back-up system for aiding a driver in backing a motor vehicle performs a number of functions when a motor vehicle is placed in a reverse direction. Initially, an image of an area at the rear of the motor vehicle provided by a camera is visually displayed on a monitor, which is positioned so as to be visually accessible by a driver of the motor vehicle. Then, a distance to an object that is within a path of the motor vehicle is sensed with a radar sensor. Next, a warning is provided when the object is within a predetermined collision distance. Finally, when the motor vehicle is placed in a forward direction, the display of the image on the monitor is discontinued.

Abstract: A system and method for digital steering sensor fault detection comprises monitoring steering wheel position information from a digital steering wheel position sensor at set time intervals, determining steering wheel position information for the current time interval and the previous time interval, and advancing a value change counter if the steering wheel position information for the current time interval is the same as for the previous time interval; monitoring vehicle speed, and advancing a speed cycle counter when the vehicle speed crosses a first threshold speed after crossing a second threshold speed; and setting fault bit information if the value change counter is zero after the speed cycle counter reaches a speed cycle limit. The steering wheel position information can be for a plurality of digital steering wheel position sensor outputs and provide corresponding fault bits, which can be compared to a fault table to diagnose a particular fault.

Abstract: A device and method for determining pulses in a modulated signal is disclosed. The modulated signal is processed and converted into a quantized analog type of digital data stream. The data stream is evaluated over time by considering preceeding and subsequent values in the data stream to generate a filtered wave form. By using extreme values in the filtered wave form pulse detection is accurately determined regardless of whether the modulated signal has complicating features, such as dicrotic notch, or high noise levels, or both.

Abstract: A temperature control system for an electrically heated cutaneous gas sensor. A heating element is provided with heating current by a closed loop temperature control circuit. The system includes a plurality of temperature monitoring circuits which are arranged to turn off the flow of heating current if the temperature of the sensor takes on an unacceptable value. The system also includes temperature setting circuitry for applying an increased temperature setpoint signal to the temperature control circuit, for a predetermined time, to reduce the time delay between the application of the sensor to the patient and the production of usable sensor data. Timing circuitry assures that the flow of heating current is not turned off in response to normal sensor temperature transients.

Abstract: An improved method and apparatus for deplating the electrodes of cutaneous oxygen sensors. A controllable voltage source selectably establishes either a polarizing voltage or a deplating voltage between the electrodes of a cutaneous oxygen sensor, while a current sensing circuit measures the current flow therebetween. If, during the calibration of the sensor, the current flow exceeds a predetermined threshold, the apparatus initiates an operator assisted sequence of operations which deplate the electrodes and restore the gas sensor to a usable operating condition. During the performance of this sequence of operations, the apparatus carries out all steps, except those which must be performed manually by an operator.

The system also includes latching circuitry for maintaining the off state of the switch after the occurrence of an out of limits condition, and circuitry for preventing the latching circuitry from being actuated during normal temperature transients.

Abstract: A fluid dispensing method and apparatus particularly adapted for post-mix dispensing of a soft drink, with accurate relative proportions of carbonated water and soft drink syrup. Separate syrup and water valves are controllably turned on and off, independently, at prescribed duty cycles, to provide a prescribed mix ratio, and syrup and water flow meters monitor the instantaneous flow rates of the water and syrup to minimize the effects of any pressure variations in the initial syrup and water supplies. The apparatus is conveniently modified for use with different soft drink syrups using a separate removable personality module for each syrup, characterizing its prescribed mix ratio and its viscosity.

Abstract: A post mix dispensing system for mixing together and dispensing carbonated water and a flavored soft drink syrup, while generating substantially reduced amounts of foam. Carbonated water is injected into a special staging chamber, where it circulates turbulently at about atmospheric pressure. The water is ported from the chamber through a plurality of elongated ports, substantially under gravitational forces alone, and the ports are configured to straighten the flow of water and remove most of its kinetic energy. A nozzle deflects the water to converge upon a stream of syrup and to mix with the syrup in an unconfined region, after a substantial proportion of the gases released from the water has escaped, thereby substantially reducing the generation of foam.
