The event detection module receives the first input signal and compares the first acceleration to an acceleration threshold indicative of a shot; receives the second input signal and determines whether the second input signal is satisfies a second threshold indicative of a shot; determines whether a discharge has occurred based on both the first signal satisfying the acceleration threshold and the second input signal satisfying the second threshold; and generates an event detection signal based on the determination.

Abstract: Web-based opinion survey method, apparatus, and computer-readable media operable to cause propositional function responses to be provided to a survey server from a client device. The propositional functions are P(x), where P and x are the predicate and subject. Each P(x) is evaluated in the client device for subjects, each with a different x. Preferably, the client device displays the subjects within a Web Single Page Application (SPA) running on the client device. Preferably, the SPA displays a nonnumerical scale, the granularity of which is directly proportional to the number of pixels spanned by the scale. For each P(x), the client device displays labeled markers along the scale, to provide an indication of a level of agreement with the expressed P(x). For each P(x) subject, the client expresses an opinion on a position on the scale, whereby a pixel position corresponds to a rating for the selected subject.

Abstract: Systems and methods are provided for preventing headwind debris from collecting on travel direction-facing housing surfaces of a vehicle by creating protective “air cushions” in front of the travel direction-facing housing surfaces. These air cushions may divert headwind air away from the travel direction-facing housing surfaces, ensuring that headwind debris does not collect on them. Examples may create these protective air cushions by propelling high pressure air through perforated surfaces in a contrary direction to headwind.
