Vehicle recorder systems are arranged in configured with a video camera, light-weight memory systems, and radio communications facility suitable for use in conjunction with an automobile. An automobile equipped with these video recorder systems used normally throughout the service today, provides a video record of unusual events which may occur from time-to-time. Events such as accidents, near-miss incidents, driving of use, among others, trigger a system to preserve video images collected before and after the moment of the event. Replay of these images yield information regarding cause and true nature of the event. These systems are particularly arranged about, and in support of fleet use of vehicles. That is, groups of vehicles are arranged and coupled together whereby a plurality of such vehicles may communicate with a common system providing a fleet manager advanced fleet management tools.

Vehicle event recorder systems are arranged to be in constant communication with remote servers and administrators via mobile wireless cellular networks. Vehicle event recorders equipped with video cameras capture video and other data records of important events relating to vehicle use. These data are then transmitted over special communications networks having very high coverage space but limited bandwidth. A vehicle may be operated over very large region while maintaining continuous communications connections with a remote fixed server. As such, systems of these inventions may be characterized as including a mobile unit having: a video camera; a microprocessor; memory; an event trigger; and mobile wireless transceivers, and a fixed network portion including: mobile wireless cellular network, a protocol translation gateway, the Internet and an application-specific server.

Vehicle event recorders are arranged with integrated web servers to provide a simple user interface and control mechanism which may be address with commonly available hardware and software. A vehicle event recorder of these inventions couples to a network having a workstation node. The workstation having either of the many available web browsers can be used to view, address, control, perform data transfer, et cetera, by way of data exchange in accordance with simple IP protocols. A vehicle equipped with these systems returns to a household to make a network connection. A local server is used to see all exposed system controls as provided by predefined web pages provided by a web server integrated as part of the vehicle event recorder unit.

A vehicle event recorder is provided that includes a camera for capturing a video as discrete image frames, and that further includes a managed loop memory and a management system for generating a virtual ‘timeline dilation’ effect. To overcome size limits in the buffer memory of the video event recorder, the maximum time extension of a video series is increased by enabling a reduction in temporal resolution in exchange for an increase in the temporal extension. Memory cells are overwritten in an ‘interleaved’ fashion to produce a reduced frame rate for the recording of certain time periods connected to an event moment. In time periods furthest from the event moment, the resulting frame rate is minimized while in time periods closest to the event moment, the resulting frame rate is maximized.

Data transfer systems for vehicle event recorders are provided as: a vehicle event recorder, a vehicle event recorder resident memory, and upload module in conjunction with, a communication port suitable for coupling with, a portable memory device, a server computer datastore, a server download module in conjunction with, a similar cooperating communications port. The portable memory device is arranged to operably couple with the communications ports of both the vehicle event recorder and the server computer and to be repeatedly moved between the two. The upload/download modules are arranged to transfer data to/from the portable memory in an orderly fashion in which no files are removed from the vehicle event recorder resident memory without first having been successfully transferred to the server computer datastore.

Vehicle operator performance history recording and reporting systems include devices and methods of automatically collecting and processing vehicle crash or event data over time to form a driver history report. A driver history report may include many factors to express performance or quality of driver service, and these may be reduced to a single value normalized expression in view of a collection of many drivers. Vehicle event recorders are arranged to capture data relating to a particular event. These vehicle event recorders are further coupled to systems which form an association between collected data and the vehicle operator in command of the vehicle at the event moment. Systems provide means for long-term storage of data particularly data in a structure which preserves the association between a driver and event records attributed to him/her. Special recall operations executed against stored data yields operator performance reporting—including a single value performance score indicative of a vehicle operator's performance and safety history. An analyzer system operates to recall data, particularly data from a plurality of events all associated with a single operator but recorded over an extended period of time. Data is arranged such that other mathematical analysis may be applied independently to various data elements or data “fields” to produce performance metrics and ratios which reflect performance. Together, these factors may each be weighted and summed in accordance with specially devised a formulae including those having a single value solution.

Tissue substance measurement systems are arranged with highly specialized optical sources. Quantum cascade lasers are high power semiconductor lasers which are tiny in size and highly tunable with respect to wavelength. When deployed in non-invasive tissue substance measurement systems, quantum cascade lasers offer system advantages such as high accuracy, small size, convenience, efficiency, among others. These specialized semiconductors may be used with systems based upon photoacoustic principles. Systems may be formed of a plurality of quantum cascade laser in an optical source, mechanism to couple light into tissue, an acoustic detector and a signal processor. In some versions, user interfaces provide a reporting and feedback function to a user.
