Abstract: One variation of a method for managing parking within a parking structure includes: after detecting a license plate number on a vehicle in an image captured by an entry camera unit arranged near an entry of the parking structure, labeling the license plate as unverified in a data log associated with the parking structure; in response to absence of validation of the license plate within a grace period after entry of the vehicle, relabeling the license plate as in-violation in the data log; in response to detecting the license plate in an image captured by a mobile enforcement unit moving through the parking structure, querying the data log for a status of the license plate; and, in response to the license plate labeled as in-violation in the data log, serving a prompt to an enforcement personnel to issue a citation to a vehicle carrying the license plate.

Abstract: One variation of a method can be implemented by a computer system (e.g., a computer network, a remote server, a local parking enforcement kiosk) in cooperation with a set of sensor units installed below restricted parking spaces (e.g., loading zones, freight parking spaces) and vehicle transmitters installed in authorized vehicles (e.g., delivery vehicles, commercial vehicles) to automatically enforce parking rules in restricted parking spaces, such as including: parking time limits; grace periods for unauthorized vehicles; billing rates for authorized vehicles; and issuance of citations for unauthorized vehicles occupying such parking spaces beyond the grace period.

Abstract: A toxic material detection apparatus includes a sample collection portion including a sample inlet and a sample concentrator adapted to concentrate an environmental sample on a substrate. A sample distributing system transfers portions of the substrate to a color sensor and an ion mobility spectrometer for simultaneously analysis and toxin detection, particularly cholinesterase inhibitor detection. Optionally, a portion of the substrate may be directed to an archive for possible analysis at a later time. Reagents utilized include the enzyme acetylcholinesterase (AChE), and the reactants acetylthiocholine iodide (ATCI) and 5,5?-dithio-bis-(2-nitrobenzoic acid) (DTB). A data management unit provides for near-real-time analysis of the samples in under 5 minutes. Simultaneous “hits” by both analysis methods indicate the presence of a cholinesterase inhibitor.

Abstract: A system, method, and computer program product for wireless network monitoring. Some particular features of various embodiments include notification via mobile phones (or other wireless devices) of outages in the wireless environment, an automated incident log, a web page to enter the resolution of an outage, a contact list containing personnel who could potential be contacted during an outage, and pop up messages that occur when an outage is detected.

Abstract: An above-ceiling system for conditioning air in a structure. The system comprises a plurality of return ducts into the inlet of the air handler, the return ducts carrying air from substantially all of the major spaces within the structure. A filter housing and filter disposed above the ceiling with an opening through the ceiling into the space below, having a cover disposed below the ceiling secured by fasteners and providing access from the space below the ceiling for removal and replacement of the filter.

Abstract: A patient ventilator system provides a controllable flow and volume of a mixed inhalation gas to a patient, and receives exhaled gas from the patient. The ventilator system includes gas flow controllers that mix air and oxygen, and provide the mixture to the patient with a controllable inhalation cycle. The ventilator system monitors the resulting patient pressures and volume of gas exhaled by the patient, as necessary. Compressed air is provided to the gas controller in the event of an absence of an external gas supply by a compressor. A controller permits the user of the ventilator system to control ventilation mode, gas pressure, composition, and flow rate of the mixed gas with a single control knob.

Abstract: A solar powered light adapted to be mounted under the eaves of a building, a wall or the like for use in security applications. In a preferred embodiment of the present invention, the solar powered light comprises an adjustable configuration having a lamp with an infrared detector or sensor rotatably mounted thereto and a photovoltaic or solar cell array rotatably disposed at a remote end of an extension arm movably attached to the lamp. Such a flexible arrangement allows the photovoltaic array to be positioned to receive direct sunlight. The sensor activates the solar powered light upon sensing infrared to illuminate the surrounding areas when a presence is sensed and turn it off when a presence is no longer sensed. In accordance with a second embodiment, the solar powered light does not include an infrared detector and provides continuous illumination for a given period of time.

Abstract: A solar powered lamp having a circuit for providing positive turn-on at low light levels causes a light source thereof to undergo a discrete transition to an "on" condition and prevents unnecessary drain on a battery thereof. The circuit comprises a positive feedback loop which amplifies current flow rapidly to a predetermined level at which the light source is illuminated. In doing so, it causes a plurality of solar powered lamps to illuminate at substantially the same time.
