Abstract: A portable mechanical ventilator having a Roots blower is configured to provide a desired gas flow and pressure to a patient circuit. The mechanical ventilator includes a flow meter operative to measure gas flow produced by the Roots blower and an exhalation control module configured to operate an exhalation valve connected to the patient circuit. A bias valve connected between the Roots blower and the patient circuit is specifically configured to generate a bias pressure relative to the patient circuit pressure at the exhalation control module. The bias valve is further configured to attenuate pulsating gas flow produced by the Roots blower such that gas flowing to the mass flow meter exhibits a substantially constant pressure characteristic. The bias pressure facilitates closing of the exhalation valve at the start of inspiration, regulates positive end expiratory pressure during exhalation, and purges sense lines via a pressure transducer module.

Abstract: Apparatus and an associated method for facilitating paging of an access terminal by an access network of a radio communication system. A quick paging message is first generated and sent to the access terminal. The quick paging message is formed of partial comparators, comprised of a first group of identity bits. A regular paging message is also generated and sent to the access terminal. The regular paging message is formed of partial comparators, comprised of a second group of identity bits. If, upon detection of the quick paging message, the access terminal determines that it is paged, the access terminal sends a response. The first and second groups of identity bits are, for example, different parts of the same number.

Abstract: Systems and methods related to the detection of incoming wireless signals. An antenna array is synthesized by having a single antenna, coupled to a receiver, spatially translated along an arbitrary trajectory. As the antenna is being spatially translated, a data processing means samples the incoming signal based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to detect an incoming signal. The invention is applicable to detecting a wireless communications signal or a GNSS signal under various conditions. The system may include at least one sensor which can provide data for use in calculating data related to the arbitrary trajectory.
