Abstract: An optical navigation device for use with mobile telephones and the like is disclosed, which has a reduced height as compared with current designs. The navigation device comprises a laser such as a VCSEL laser, an exposed user surface and two other surfaces that provide for total internal reflection of the incident laser beam. The surfaces are constructed with shallower than normal angles, preserving the basic functionality of the device while reducing the height.

Abstract: A proximity sensor includes a sensor package having an attachment pad with a radiation source and a radiation detector housed within the sensor package. The source and the detector are held in a fixed relation to the attachment pad, and are mounted by one of a direct or indirect attachment to the attachment pad. A portion of the attachment pad is adapted to form a baffle which forms at least part of an optical isolator. The optical isolator is adapted to substantially prevent the internal propagation of radiation between the source and the detector within the sensor package.

Abstract: The internal propagation of radiation between a radiation source and radiation detector mounted within a sensor package is prevented by the use of an optical isolator. The optical isolator is formed by the combination of a baffle mounted between the source and detector and a groove formed in an upper surface of the sensor package between the source and detector. A bottom of the groove is positioned adjacent to an upper edge of the baffle.

Abstract: Novel tools and techniques to optimize, from a merchant's perspective, the outcomes of interactions between the merchant and its customers (whether existing, new, or potential customers). In an aspect, certain embodiments allow for multiple variations of options (multivariate or A/B testing) and outcomes which can be statistically applied and then measured and analyzed for best economic impact or preferred outcome.

Abstract: An optical navigation device may include an image sensor with an imaging surface, a laser, and an optical waveguide layer having an exposed user surface and a total internal reflection (TIR) surface on the underside of the exposed user surface. The waveguide layer, the laser, and the image sensor may be together arranged to direct radiation emitted by the laser onto the imaging surface at least partly by total internal reflection by the TIR surface.

Abstract: A lens mounting assembly includes a lens barrel with a first lens assembly. A lens mount includes an image sensor, and the lens barrel matingly connects with the lens mount in a manner which allows the first lens assembly to be moved along an optical axis to adjust a focus on the image sensor. A second lens assembly is provided for adjusting the focus on the image sensor during use of the lens. An alignment projection is provided on at least one of the first or second lens assemblies, the alignment projection being adapted to mate with a portion of the other of the first or second lens assemblies in order to directly optically align the first and second lens assemblies with the image sensor.

Abstract: An apparatus includes an inverter including a high-side switch coupled to a low-side switch, the inverter generating a time-varying drive current from a plurality of drive control signals, a positive rail voltage, and a negative rail voltage wherein controlling the switches to generate the time-varying drive current produces a potential transitory overshoot condition for one of the switches of the inverter; a drive control, coupled to the inverter, to generate the drive control signals and to set a level of each of the rail voltages responsive to a plurality of controller signals; and a controller monitoring one or more parameters indicative of the potential transitory voltage overshoot condition, the controller dynamically adjusting, responsive to the monitored parameters, the controller signals to reduce a risk of occurrence of the potential transitory voltage overshoot condition.
