摘要:
A control system for controlling an object function includes a base station and a portable code transmitter. The base station is at the object and has a transceiver unit for transmitting an interrogation signal. The code transmitter emits a response signal with a code information item in response thereto. The base station checks an authorization of the code information item contained in the response signal. The base station and/or the code transmitter determines a time period between a transmission of a part of the interrogation signal and a reception of a part thereof obtained in reaction thereto, and compares the time period with a predefined reference time period. The base station enables the object-specific function only if the measured time period is shorter than the reference time period even if the code information item of the response signal is correct. There is also provided an access control and driver authorization device for a motor vehicle where the base station transmits the interrogation signal to the code transmitter from which checkbits are transmitted back directly to the motor vehicle, bypassing an evaluation unit. The base station measures the time period between the checkbits being emitted and received back and only accepts a response signal of the code transmitter if the measured time period is shorter than a reference time period. There is also provided a method for controlling at least one function of the object.

A measuring fishing net for holding and measuring a size of a fish and a method of use of the net, including a frame having a handle and a substantially enclosed loop. The frame further having an axis extending in a direction parallel to the frame and a net attached to the loop of the frame, for holding the fish. A measuring scale runs linearly along the axis and length markings are disposed on the loop of the frame, to measure the size of the fish by comparing the fish to the length markings.

A system and method is provided for enabling respondents at their computer systems to connect via a browser with a server computer over a network, such as the Internet, and receive an initial set of survey questions on one or more pages during which primary images are downloaded into the browser's cache but are not presented to each respondent as they are each displayed into a small (e.g. 1 by 1) pixel area on display of the respondent's computer system and thus are not detectable by respondents. After receiving answers to such questions for each of the respondents, the server computer directs the browser of each respondent computer with at least one survey question in which the primary image is displayed from the browser's cache for a brief interval of time to the respondent, and the respondent answers the question with respect to the primary image. Different survey questions may be presented to the respondent having different timed displayed primary images. The results of the survey questions and the answers after each timed displayed primary image are registered at the server computer. The primary images may be images of store shelves of different product packages, advertisements, or product having different features, in which the questions relate to recall or findability of a target element, such as a product package, a feature of an advertisement, or a product feature, respectively, in the primary image.

摘要:
Antennas of an anti-theft system are controlled with a pulse width modulated square-wave signal by a power control unit and a phase control unit. The control is such that a change in power causes no change in phase, and vice versa. This is accomplished by varying the pulse width of the square-wave signal if a change in power occurs and at the same time shifting the pulse rise time such that the phase remains constant.

An auto gripper molding having a notch in the surface of its inner crown overhang in facing relation to the windshield exterior surface which notch serves firstly to receive an end of the molding gripping leg having accordingly a desired longer length, and serves secondly to have deposited therein, after the gripper leg is moved into its windshield-gripping location, a viscous mass of urethane which cures in the notch and provides a mechanical interlock between the gripper molding and the windshield.

A stationary rectangular-shaped auto window without any weather seal applied to its peripheral edge resulting in a window-enhancing gap in encircling relation about the window and, having as a substitute for the weather seal, a rectangular deposit of urethane inwardly of the rear surface of the window which seals water seepage through the gap and also holds the window firmly in place on a supporting flange.

A cyclops light as now mandated by law on the panel above the rear doors of a van is relocated as side-by-side lights to the inside adjacent corners of the doors and each provided with a triad of lens so that, when a door is open, as when loading and unloading the van, the light now seen through the triad lens is a safety signal to a motorist approaching from the rear, and the light seen through the previously used rear lens is still in use, but as a safety signal to a motorist approaching from the front in a passing lane.
