Abstract: Described is a dynamic emergency exit sign comprising one or more pictograms and at least one light source for accentuating one or more of the one or more pictograms either singly or in combination, wherein at least one light source is controlled by signals from evacuation computer modelling software to assist occupants egress in emergency or other critical situations.

Abstract: Disclosed is a drowsiness prevention system installed in a vehicle. The drowsiness prevention system includes: a light emitting unit irradiating infrared light toward the driver's iris, an infrared camera capturing images of the driver's iris, and a warning sound generating unit determining the driver to be drowsy to generate a warning sound when the driver's iris is not detected from the images captured by the infrared camera within a preset reference time. The distribution angle pattern of the infrared light is inclined from a central axial line. The light emitting unit is mounted in an area other than the driver's front area.

Abstract: A computer-implemented method and system for controlling vehicles in a vehicle convoy. The vehicles in the vehicle convoy include a following vehicle and a preceding vehicle positioned immediately ahead of the following vehicle. The method includes receiving vehicle convoy data about an environment surrounding the vehicle convoy, and detecting an intention of a remote vehicle to execute a cut-in maneuver into a path of the following vehicle. The method includes controlling a vehicle system of the following vehicle to project a status indication to a ground surface between the following vehicle and the preceding vehicle. Further, the method includes determining whether the cut-in maneuver is acceptable based on the intention of the remote vehicle and a distance between the following vehicle and the preceding vehicle, and controlling the following vehicle based on whether the cut-in maneuver is acceptable.

Abstract: A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

Abstract: An envoy device configured to perform a transaction with a further device. The envoy device comprises: a data store; a processor; communication circuitry for communicating with the further device; and a display. The envoy device is configured to respond to detection of the further device being within a predetermined physical proximity to trigger initiation of a transaction between the devices; and to respond to the transaction completing to display an object related to the transaction that it is determined the user may wish to select to initiate a subsequent action.

Abstract: A non-contact voltage detector module pluggable to a mobile communication device. The non-contact voltage comprises an antenna, a connector configured for connecting to a connector of a mobile communication device, and an assembly coupled to the antenna and the connector. The assembly converts an electromagnetic field received by the antenna to an indication of a strength of the electromagnetic field and transmits the indication of the strength of the electromagnetic field via the connector.

Abstract: Systems and methods for location determination using radio frequency tags are disclosed. In one embodiment, a method may include (1) a back end server receiving, from a RF sensor in a network comprising a plurality of RF sensors, a unique identifier for a sensed tag and an identifier for the RF sensor; (2) the back end server retrieving a location of the RF sensor based on the sensor identification; (3) the back end server associating a sensed tag location with the location; (4) the back end server retrieving authorization information for the sensed tag based on the unique identifier; and (5) the back end server determining that the sensed tag is authorized to be in the location.

Abstract: A parking exchange application method and system for securing an available parking space on a street corner. A responding driver in a car temporarily occupies an available parking space and informs a central processing database of the address of the available parking space. A requesting driver searching for an available parking space in a location vicinity, transmits a request to the central processing database. The central processing database compiles a list of available parking spaces addresses, and the requesting driver selects one of the available parking spaces, and drives toward the selected available parking space. Upon arrival, the central processing database makes payments of a transfer fee to the requesting drive, in exchange for the selected available parking space, and a commission fee to the parking exchange application, from an authorized fee payment from the requesting drivers, and the requesting driver occupies the available parking space.

Abstract: A brake warning light is applied to a rear portion of a vehicle and includes a left brake light, a right brake light and an extended brake light assembly. A first left segment of the left brake light is aligned with a first end of the extended brake light assembly along a direction of a first extension line. A second left segment of the left brake light is aligned with a first right segment of the right brake light along a direction of a second extension line. A second right segment of the right brake light is aligned with a second end of the extended brake light assembly along a direction of a third extension line. When the vehicle is braked, the left brake light, the right brake light and the extended brake light assembly are lit and viewed as a planar warning pattern to enhance warning effect.
