Abstract: A dual phosphor wheel projection system is provided. A first dichroic mirror directs blue light from a first blue laser to a second dichroic mirror which directs the blue light to at least one integrator. The first dichroic mirror directs blue light from a second blue laser to a first phosphor/phosphor wheel, which converts the blue light to longer wavelengths that includes red light. The second dichroic mirror directs the red light to the integrator and transmit others of the longer wavelengths. The integrator combines the red light with red light from a red laser. A third dichroic mirror directs the red light from the red laser to the integrator and directs blue light from a third blue laser to a second phosphor/phosphor wheel, which converts the blue light to respective longer wavelengths that includes green light. The third dichroic mirror transmits the green light to the integrator.

A device determines a target-destination wave, representative of an image, to be formed at an image plane of the PLM using image data, defining the image for projection, and a random seeding of spatial values of a spatially varying phase of the target-destination wave at the image plane, the image plane located between the PLM and SLM, the SLM and PLM arranged such that light reflected from the PLM illuminates the SLM. The device determines a target-source wave to be formed at the PLM, based on: a free space transfer function between the PLM and the image plane; and the target-destination wave. The device determines, from the target-source wave, a phase map for controlling the PLM to form the image. The device controls the PLM using the phase map.

Abstract: Apparatus and methods for blood analyte sensing, data processing, and transmission and storage. In one embodiment, the sensor comprises a spatially compact multi-element implantable blood glucose sensor apparatus which is configured to generate signals or data relating to sensed blood glucose levels of a host being, and process the data in vivo to generate e.g., data suitable for transmission to an external receiver device for storage and indication. The implanted sensor apparatus may also determine the need for an alert. In one variant, the sensor apparatus provides for ultra-low energy consumption through a number of coordinated mechanisms, including only issuing wireless transmissions (advertisements) when communication is needed, and use of multiple “layered” operating modes. Reduced energy consumption advantageously also extends implantation longevity and reliability/availability.

Abstract: Receiver apparatus for use with an analyte sensor, and methods of operation and manufacturing. In one embodiment, the analyte sensor is an implanted/implantable blood glucose sensor, including oxygen-based detector elements. The receiver apparatus is a wireless-enabled small form-factor device with limited functionality that can be easily worn or kept with the user on a continual basis, thereby obviating the need for a more fully featured receiver or smartphone for extended periods of time (e.g., one week). The exemplary oxygen based analyte sensor, with high degree of stability over time, enables the user to divorce themselves from the more fully functioned receiver or smartphone, since no external calibration of the sensor is required during the extended period. In one variant, the device is a lightweight wristband. Other variants include e.g., pendants, finger-worn rings, arm or head bands, skin patches, and even dental, subcutaneous, or prosthetic implants.

In some implementations, the control unit may additionally set a threshold value for communication to a comparator to compare against the total measure of energy and in response control the width of the active light pulse.

The prime modulator can be oriented to receive defocused light from the relay optics at the light input face of its TIR prism system. The pre-modulator can be oriented backwards, so as to receive source light at the on-state face of its TIR prism system and to output pre-modulated light to the relay optics via the light input face of the TIR prism system.

Abstract: A source light beam is split into an illumination beam and a highlight beam. The highlight beam can be controllably shaped into a shaped highlight beam based on a brightness analysis of an image to output. The illumination beam and the shaped highlight beam are combined and provided to an imaging device that generates the image using the combined beam. An array of reflectors, such as a MEMS mirror device, can be used in conjunction with a stacked rod array to generate the shaped highlight beam. The illumination beam and the shaped highlight beam can be combined using offset lenses or a polarizing beam splitter.
