Abstract: The system for use with a breath tester includes a computing facility. In a learning mode, the facility is adapted to: receive the weight of a user; receive the details of each drink consumed by a user and the time of consumption of said each drink; receive measurements of breath alcohol content produced by the breath tester; and calculate the elimination rate of the user. In a predictive mode, the facility is adapted to: receive the details of each drink consumed by a user, and the time of consumption of said each drink; and calculate the expected breath alcohol content of the user based on the weight of the user, the calculated elimination rate of the user and said details of each drink consumed by the user and said time of consumption of said each drink.

Abstract: A system for use with a motor vehicle, the system including a gas sampler device including a wireless communication subsystem and an input element configured to receive a gas sample. The system further includes an interlock device including a second wireless communication subsystem and a computing device configured to: determine a location of the gas sampler device within the motor vehicle based on proximity of the wireless communication subsystem, and activate an alarm event in dependence of the location of the gas sampler device within the motor vehicle.

Abstract: The method includes a dictionary including a target collection defined by images that are known with a defined level of certainty to include a subject and an imposter collection defined by images of individuals other than the subject. In the method, images of an area are captured over a period of time. In respect of each image: a matching calculation is carried out, based upon a comparison of the image captured with the images in the dictionary to result in a measure of confidence that the subject is in the area; and an inference determination is made to replace one of the target collection images with a further image that is known with the defined level of certainty, the determination being a function of the measure of confidence resultant from the captured image, the measure resultant from one or more previously captured images and the associated capture times.

Abstract: A method for use with a stream of images defining a video. The method includes the steps of periodically conducting a face finding operation on an image in the stream. In respect to the last image in the stream preceding the image in which one or more faces was found, a tracker based upon wavelet decomposition is used to find a face for each face found in the last image for which no counterpart was found in the image.

Abstract: The system is of the type for use by a person and including a handpiece and an imaging device, the handpiece containing a breath alcohol tester and the imaging device being adapted to capture an image including the handpiece when a breath sample is delivered to the handpiece. The improvement includes a sensor arrangement and a computing functionality. The sensor arrangement is adapted to provide information from which an orientation and position of the handpiece can be calculated. The computing functionality is adapted to: generate a calculated orientation and position of the handpiece; and if a face appears in the image, precisely locate the features thereof. The features of the face are located using the calculated orientation and position of the handpiece.

Abstract: Apparatus for use with a vehicle is disclosed and comprises an interlock device. The device is adapted to, in use: at least while said vehicle is in motion, periodically generate a prompt; assess motion of said vehicle; at least when said vehicle is assessed by said device to be at rest, carry out an analysis operation wherein a breath sample is received and analyzed; and in the event that, within a predetermined period following a prompt, the device does not, while said vehicle is assessed to be at rest, carry out said analysis operation, enter an alarm state at least when the vehicle is in motion. The device can be adapted to carry out analysis operations only when the vehicle is assessed to be at rest.

Abstract: An improved ignition interlock system being of the type including a plurality of ignition interlock devices. A vehicle is provided in which each device is installed. The plurality of service centers are provided with each service center having an associated computer adapted to extract data. A wireless transceiver is associated with each device. A wireless transceiver is associated with each service center. Computing functionality is associated with the service centers and with the devices and adapted such that when any of the vehicles attends any of the service centers, the computer associated with that service center can extract the data from the device disposed within that vehicle.

Abstract: The apparatus, which is used with a vehicle, comprises a breath alcohol sensor and a computing device. The computing device is operatively coupled in use to the sensor and the vehicle and configured to record data: which provides information indicative of the likelihood that the vehicle has been operated in circumstances wherein a breath sample has not been delivered to the sensor within a predetermined period preceding the commencement of said operation; and associated with the delivery of breath samples to the sensor that contain alcohol in excess of a predetermined threshold.

Abstract: The apparatus is for use with a motor vehicle operated by a driver and includes a scanning device and a computing facility. The scanning device, in use, gathers information about the eye activity of the driver. The computing facility determines, based on the information gathered, whether the driver is watching the road. The determination can include one or more of: ascertaining an orientation of at least one of the driver's eyes; and ascertaining an orientation of the head of the driver. The computing facility can be defined by a microprocessor. If the facility determines that the driver is not watching the road, the facility can trigger an alarm state of the vehicle. The apparatus can be employed for persons convicted of driving while texting in a manner analogous to the manner in which breath alcohol ignition interlocks are employed for persons convicted of driving under the influence of alcohol.

Abstract: A portable breath analyzing device to measure the rate of partial gas that is exhaled in the breath fluid. The device includes a rechargeable power supply unit, a device to emit pulsated infrared radiation, an infrared receiver, and a measuring vessel. The emission device includes a heating element; the measuring vessel includes a metallic tube whose interior surface is polished and coated with a deposit that reflects at least the infrared radiation of wavelengths that are between (9 ?m, 10 ?m) and at each end of the tube, a nozzle comprising a cone-shaped section meant to be placed in the tube axis. The infrared emission device is placed on the longitudinal axis of the tube, at the level of one of the nozzles, and the receiver is placed on the longitudinal axis, at the level of the other nozzle.
