Abstract: A tracking system includes a hub coupled to a client device, such as a computer or mobile phone, and one or more tags configured to wirelessly communicate with the hub. The hub includes a web server and a radio frequency transceiver. A browser executing on the client device exchanges data with the web server included in the hub, allowing location of the one or more tags via the client device without installation of a dedicated application on the client device for communicating with the hub or with the one or more tags. Additionally, the client device may communicate with a remote server via a network to communicate with additional tags via the browser executing on the client device. The hub transmits an activation request to the one or more tags via near field communication, radio frequency communication, or another suitable wireless communication method.

Abstract: A pill feeder accepts a quantity of pills and organizes the pills into a single file where each pill is output in a controlled orientation at a controlled rate. The apparatus includes a moving surface, such as a rotating disk, to receive and move pills past one or more gates that separate and orient groups of pills into a single file. The gates can start at a closed position and open until a pill has passed the gate. In one embodiment, a mixer counter-rotates relative to the rotating disk to prevent jams of the pills. The single file of pills is then guided out to an exit chute via an exit path. An alternative exit path provides an alternative route via which the pills exit the pill feeder. Multiple sensors can control the movement of the gates and the rate at which the pills exit the pill feeder.

Abstract: A speed sensor determines the velocity of an object. A first detector detects light emitted by a first emitter. The first detector includes multiple photodetectors connected in series. The photodetectors produce a current that is proportional to the amount of light incident to the photodetector. The first detector additionally includes a current-to-voltage converter and a threshold detector. The current-to-voltage converter converts the current produced by the photodetectors into a voltage and the threshold detector compares the voltage generated by the current-to-voltage converter with a threshold voltage. When an object passes in between the emitter and any of the photodetectors, the light incident to the photodetector is at least partially blocked, reducing the current produced by the photodetector.

Abstract: A pill identification system identifies a pill type for a pharmaceutical composition from images of the pharmaceutical composition. The system extracts features from images taken of the pill. The features extracted from the pill image include color, size, shape, and surface features of the pill. In particular, the features include rotation-independent surface features of the pill that enable the pill to be identified from a variety of orientations when the images are taken. The feature vectors are applied to a classifier that determines a pill identification for each image. The pill identification for each image is scored to determine identification for the pharmaceutical composition.

Abstract: A pill verification system obtains a prescription filled at a pharmacy and gathers information of the pills being dispensed for a remote pharmacist to verify the prescription. As pills are dispensed to a pill vial to fill the prescription, a pill imaging system captures images of the pills, and a pill vial imaging system captures an image of the pill vial. The prescription, pill images, and pill vial image are transmitted to a remote verification system. A pharmacist is presented with the prescription, images of substantially all pills filling the prescription, and the pill vial of the prescription to verify the prescription is correct. The remote verification system may present prescriptions filled from many different pharmacies, permitting increased rate of verification and one pharmacist to support many pharmacies. The pharmacist's verification is transmitted to the pill verification system and displayed for a technician to complete verification of the pills.

Abstract: Disclosed is a system and method for delivering digital audio/visual content over a facilities analog-based television network, such as the cable network of a school. An administrator is provided that includes a video server, a DVD/decoder, a controller for the DVD/decoder, and a modulator. The system enables the school to access video on demand while bypassing its existing computer network. This avoids congesting the computer network with the streamed video.

Abstract: A snapshot backscatter radiography (SBR) system and related method includes at least one penetrating radiation source, and at least one substantially transmissive radiation detector. The substantially transmissive radiation detector is interposed between an object region to be interrogated and the radiation source. The substantially transmissive radiation detector receives and detects forward radiation from the radiation source before transmitting a portion thereof to interrogate the object region, wherein a portion of backscattered radiation provided by the object region is detected by the detector. A changeable collimating grid having a plurality of spaced apart radiation absorbing features is coupled to structure changing a position of the plurality of features and is disposed in at least one of the path of the forward radiation and the path of the backscattered radiation.

Abstract: A reconfigurable collimated radiation detector, system and related method includes at least one collimated radiation detector. The detector has an adjustable collimator assembly including at least one feature, such as a fin, optically coupled thereto. Adjustments to the adjustable collimator selects particular directions of travel of scattered radiation emitted from an irradiated object which reach the detector. The collimated detector is preferably a collimated detector array, where the collimators are independently adjustable. The independent motion capability provides the capability to focus the image by selection of the desired scatter field components. When an array of reconfigurable collimated detectors is provided, separate image data can be obtained from each of the detectors and the respective images cross-correlated and combined to form an enhanced image.
