Abstract: Described is a device for electronic access control (EAC) and surveillance. The device includes an EAC module and an imager integrated in a single unit. The EAC module controls physical access through a secure portal and the imager maintains surveillance of an observation area near the portal. A data signal is provided at a data port proximate to the EAC module and imager. The data signal includes EAC data for the portal, image or video data of the observation area and optional audio data. The device can be configured to communicate with a remote server and database over an IP data network. The device can also include one or more analytical modules for real-time computation and processing of data and generation of metadata for transmission over the data network. Correlating and combining current and historical data from multiple devices results in powerful real time threat detection and forensic search capability.

Abstract: A system for inventorying and distributing potted plants for a greenhouse includes a system of elevated rails disposed throughout the greenhouse. Rolling benches travel on the system of rails so that the potted plants may be transported to and from proper growth positions in the greenhouse. Plants that are ready to be shipped to retailers are tagged with labels via hog rings and loaded from a rolling bench onto a spacer tray that features receptacles sized so as to prevent the plants from tipping during transport. A number of spacer trays are loaded onto a rolling plant rack for delivery to a retailer's store via a delivery truck. Filled plant racks are rolled off of the delivery truck and into position at the retailer's store and exchanged for empty plant racks. The plant racks feature shelves that are spaced to allow easy plant maintenance in the store. The shelves are also tilted to allow display of the plants.

Abstract: A method and apparatus for the measurement of a property of particles suspended in a medium are described. In one embodiment, the deformability of sampled red blood cells is measured. A pulse generator (40) provides a narrow square pulse to a transmitting transducer (35), which passes an ultrasonic wave through the sample medium (15) to be received by a receiving transducer (36). The output signal from the transducer (36) is amplified by an amplifier (41) then subjected to signal processing. The acoustic absorption of the sample is calculated and scaled with frequency. The slope of a plot of scaled absorption with frequency gives a measure of the red blood cells' deformability.
