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: 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: A sobriety interlock of the type connectable to a machine such as a vehicle and normally operating to disable the machine from starting unless a breath sobriety test is passed, is equipped with a service reminder timer operable to initiate an appropriate indication when the interlock is due to be serviced and optionally, to provide one or more advance indications prior thereto. In the event the interlock is not serviced when due or within an optional grace period thereafter, appropriate action is preferably initiated. In one alternative form, this action includes disabling the vehicle or other machine to which the interlock is connected, regardless of whether a sobriety test or other condition normally imposed by the interlock is satisfied, until timely service is obtained. In a second alternative form, the sobriety interlock of the invention does not disable the vehicle for failure to obtain timely service.

Abstract: A sobriety interlock is connectable to a machine such as a vehicle and normally operates to disable the machine from starting unless one or more preconditions, such as the passage of a breath sobriety test, is satisfied. In the event the interlock is bypassed,i.e. the machine started without a prerequisite condition being satisfied, the bypass event is detected and recorded. The record of bypass events preferably includes an indication of each time interval, such as a day, during which at least one bypass event took place as well as the total number of bypass events detected since the sobriety interlock was installed or last serviced. Also disclosed is a remote service device connectable to the interlock by service personnel and useful for such purposes as reading and/or clearing the record of bypass attempts.

Abstract: A sobriety interlock system prevents a vehicle or other equipment from being started unless the identity of a designated operator is confirmed by the system and the operator passes a breath sobriety test. The designated operator is trained to perform a physical act, the successful completion of which can be determined by the system and which requires at least a predetermined number, N, of attempts to learn. A necessary precondition for starting the vehicle is satisfied when the system determines that the identity-confirming act has been performed in fewer than N attempts.
