Abstract: An electronic device package comprises a primary microphone having a frequency response having a first resonance frequency, and a reference microphone having a frequency response including a second resonance frequency, the primary microphone and the reference microphone configured to substantially simultaneously receive a same acoustic signal to produce a transduced signal of the primary microphone and a transduced signal of the reference microphone, the second resonance frequency of the reference microphone being different than the first resonance frequency of the primary microphone, the package having dimensions that cause the primary microphone and reference microphone to be acoustically isolated from one another at the resonance frequency of the primary microphone, there being less than 3 dB of acoustic coupling between the primary microphone and reference microphone at the first resonance frequency.

Abstract: Devices and methods for capturing vehicle undercarriage images are described. In some instances, a mirror assembly may be used to reflect images of portions of a vehicle undercarriage into a field of view of a camera to be captured, e.g., as a vehicle passes over the mirror assembly. Composite images may be reconstructed from the reflected portions of the vehicle undercarriage, and analysis may be performed on those reconstructed, composite images to identify features in the composite vehicle undercarriage images.

Abstract: A method of making an acoustic sensor (e.g., a piezoelectric sensor for a piezoelectric microelectromechanical systems microphone) includes forming or depositing one or more piezoelectric layers to define a beam extending between a proximal portion and a distal tip (e.g., unsupported free end), the beam having a width in plan view that is greater at a location distal of the proximal portion than at the proximal portion. The method also comprises attaching the beam to a substrate in cantilever form so that the proximal portion of the beam is anchored to the substrate and the distal tip is a free unsupported end of the beam. One or more electrodes are disposed on or in the proximal portion of the beam.

Abstract: A method and system is provided for splitting a print job into its preamble and at least one chunk. The splitter maintains a collection of RIP node addresses to which chunks of the job currently being split have already been sent. When a new chunk is about to be sent, the splitter checks whether each RIP node address has already received a chunk. If the RIP node has not already received a chunk, the splitter sends the preamble as well as the chunk to an available RIP associated with the RIP node. If, however, the RIP node address has already received a chunk, only the portion of the chunk after the preamble is sent to an available RIP associated with the RIP node and communicate the location of the preamble to the available RIP node. The preamble may contain common content for each job.
