Abstract: The disclosure describes methods of fabricating a single-piece housing for an electronic device using an injection molding process. Illustrative fabrication processes describe variations of positioning internal components of an electronic device into a mold enclosure and injecting a foam material to produce a single-piece housing that surrounds the internal components. The single-piece housing may be fabricated to provide the electronic device with at least some buoyancy, as well a means to expel thermal radiation emanating from internal components. Further, the fabricated single-piece housing provides enough structural rigidity to protect internal components of the electronic device from damage, while retaining some malleability to flex without damage when an external pressure is applied.

Abstract: Systems, devices, methods, computer-readable media, techniques, and methodologies are disclosed for increasing efficiency in power management for user devices. In some embodiments, a system voltage and battery voltage of a user device may be monitored and stored. The system voltage and battery voltage may be analyzed, and a system minimum voltage threshold for a user device may be modified based on the analysis of the measurements.

Abstract: A method of wireless communication in a lossy environment entails generating a direct sequence spread spectrum (DSSS) code string that includes a pseudo-noise (PN) sequence followed by instances of shifted PN sequences, where the shifted PN sequences are produced in response to the content of the message. The PN sequence includes a plurality of chips arranged in a first order, and each of the shifted PN sequences includes the plurality of chips arranged in another order. A beacon signal modulated by the DSSS code string is transmitted from a transceiver and received at a receiver within the communication system. Correlation peaks are formed at the receiver, where each correlation peak is associated with one of the PN sequences or one of the shifted PN sequences. Shift values are determined from the correlation peaks and the shift values are decoded to produce the message at the receiver.
