Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether movement is detected within a predetermined area. One or more parameters of illumination or modulation may be dynamically adjusted based on the present operating mode.

Dynamic conservation of imaging power

A method for calibrating a 3D camera includes determining an actuation of an element by a person and calibrating the 3D camera based on the determining of the actuation.

Calibration of a 3D camera

Embodiments relate to indirect tire pressure monitoring systems (TPMSs) and methods that utilize anti-lock braking system (ABS) signals. In embodiments, information from the ABS Hall signal is obtained in analog form, before pulse forming. The information can be analyzed for a resonance frequency within the ABS sensor. In some embodiments, the digitized information can be modulated onto the conventional ABS wheel speed clock signal for transmission to and analysis by the indirect TPMS electronic control unit (ECU). According to embodiments, additional information about higher-order harmonics of the wheel rotation can be provided to the TPMS ECU, which can then calculate a more accurate estimation of tire pressure while reducing warning latency.

Indirect tire pressure monitoring systems and methods

A method for controlling at least one control parameter of a control element comprises determining first information indicating a distance between a part of a human body and a reference. Based on the first information, determining second information indicating a transformation relation between a gesture movement of the part of the human body and an effected change of the control parameter by the gesture movement. The transformation relation is modified based on a change of the distance between the human body and the reference.

Control of a control parameter by gesture recognition

Embodiments relate to unidirectional TPMS utilizing information from a corresponding vehicle system in order to correlate with vehicle speed information to be used in a tire localization methodology. In an embodiment, the vehicle system is an anti-lock brake system (ABS), and the vehicle speed can be used in a localization scheme that reconstructs a +/&#x2212;1 g ripple with waveform, amplitude, frequency and phase parameters. Because the waveform is known to be sinusoidal (due to the wheel rotation), the amplitude is known to be 2 g peak-to-peak (due to the gravitational +/&#x2212;1 g), the frequency depends on vehicle speed (which can be estimated from centrifugal force measurements), and an algorithm is discussed herein for determining the phase by correlation, the +/&#x2212;1 g ripple can be reconstructed and the wheels localized therefrom.

Methods of wirelessly communicating are disclosed. In one embodiment, a transmit angle along a circumference of a revolution is determined, a transmit time of the transmit angle based at least in part on a time required to complete a revolution is determined, and a signal is wirelessly transmitted at the transmit angle and the transmit time. Apparatuses and systems are also disclosed.
