    摘要: A reverse current protection system for a vehicle electrical system that communicates with a trailer electrical system generally includes a mode determination module that receives a reverse current flow detection signal and that selectively determines a field effect transistor (FET) operating mode to be a reverse on mode based on the reverse current flow detection signal. A current flow control module generates a current flow control signal to a field effect transistor to control the field effect transistor based on the determined FET operating mode.

    摘要: A display for measured quantities can include a gauge with a set of indicia spaced around the gauge to indicate the measured quantities. A window can be formed in the gauge that extends along the set of indicia. An elliptical reflector can be positioned such that a first focus of the elliptical reflector is on the same axis as the center of the gauge with this axis perpendicular to the axis connecting the foci. An optical device can be mounted on a shaft and be arranged to redirect a light beam from a second foci of the elliptical reflector onto the elliptical reflector to generate a virtual pointer in the window. Means can be provided for turning the shaft to rotate the optical device. A light source can project the light beam onto the optical device. Rotation of the optical device can enable the virtual pointer to be selectively aimed at the set of indicia.

    摘要: Systems, computer-readable media, and methods for generating search engine results pages are provided. A user provides a search engine with one or more query terms. The query terms may be associated with an intent, e.g. product entity, store entity, person entity. The search engine classifies the query and identifies search results that correspond to the query. The search results are grouped based on intents associated with the query. A graphical user interface displays the grouped on search results and allows the user to modify the groupings. The graphical user interface is also updated with entity or entity attributes corresponding to the intents used to group the search results.

    摘要: A user interface display system can include at least one user responsive element. The user responsive element can include an optical mechanism. A pulsed light source can produce a light beam. Apparatus are provided for causing the light beam to repeatedly scan across the activity field. A controller can be arranged to repeatedly turn the light source on at one or more predetermined scan positions to illuminate the user responsive element. The controller can also be programed to act upon a signal regarding the status of the element. A photo detector can send the signal to the controller. The optical mechanism acts upon the light beam differently based upon the status of the user responsive element.

    摘要: A display for measured quantities can include a dial plaque with at least one set of indicia spaced around the plaque to indicate the measured quantities. An optical device can be mounted on a shaft within a perimeter of the dial plaque at a location surrounded by the indicia. The optical device can redirect an incident light beam onto the area of the set of indicia. A motor can turn the shaft to rotate the optical device through three-hundred-sixty degrees about an axis of rotation centered on the shaft. Apparatus can be provided for sensing the shaft rotating angular position. A light source can project a light beam on the optical device through the axis of rotation, such that a virtual pointer is generated.

    摘要: A method for controlling a lamp circuit that includes: setting a first voltage threshold and a first time window within a control circuit corresponding to a characteristic of a first lamp type; providing a first signal through the lamp circuit to start a first time interval and create a first test voltage; comparing the first test voltage to the first voltage threshold; and operating a switch to couple an output of the lamp circuit to a source of electrical power if the first test voltage is greater than or equal to the first voltage threshold before the first time interval exceeds the first time window.
