Abstract: Method of analysing at least one parameter of a body component is provided. The method includes illuminating the component or body with light of at least a first and second waveband, receiving light of at least said first and second wavebands remitted by the component at a photoreceptor or photoreceptors, and analysing the light received at the photoreceptor(s) to provide a ratio between the amount of light remitted of the first waveband and the amount of light remitted of the second waveband, and from this calculating the component parameter.

Abstract: An image of an individual (2) is obtained using a digital camera (1). The image data is then processed by ratio determination module (10) and an image conversion module (12) to analyze the image and determine data representative of the distribution of blood and melanin in the skin of the imaged individual. This chromophore distribution data is then processed by an image generation module (18) which generates an image representative of the expected appearance of epithelial tissue having the determined distribution of chromophores where the epithelial tissue is under fixed illumination and has a flat spatial geometry and where all the identified melanin is present solely in the epidermis.

Abstract: An image of an individual (2) is obtained via a digital camera (1). The RGB image data is then processed to derive from the image data data representative of the distribution of chromophores resulting in the appearance of the individual (2). A calculated chromophore distribution is then utilised to derive a revised chromophore distribution representing the effect of the desired cosmetic or surgical intervention or medical condition. This chromophore distribution is then processed to generate an output image (34) illustrating the expected result of that intervention. The generated image (34) can be displayed simultaneously with an original image (33) so that the extent of expected improvement can be determined.

Abstract: A multi-user vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and one or more central hosts. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of DataPoint Records (DPRs) in an on-board non-volatile (e.g. flash) memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. Although the DPRs are stored in permanent storage on the gateway, they are deleted from permanent storage on the gateway after they are successfully uploaded to the central hosts. The gateways are shared, and communicate with the central hosts over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to selected central hosts.

Abstract: A boat trailer washing system is used after a trailer has been immersed in a body of water to cleanse the same from any salty residue which will easily and quickly have a detrimental effect on the structure of the trailer. The frame of the trailer has longitudinal water pipes installed thereon which carry a multiple of nozzles directed to the frame in one direction. The trailer hitch has a water tank mounted thereon which is the source of water for a pump located on the trailer. When the pump is activated, it will draw water from the water tank, pressurize the water and deliver the water under high pressure to the nozzles located on the water pipes. The water pipes may be rotated so that the water pressure may be directed to a hull of a boat located on the trailer.

Abstract: A vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and a central host. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of Data Point Records (DPRs) in an on-board flash memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. The gateways communicate with the central host over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to the central host. Databases in the gateways as well as in the central host are maintained and synchronized to track received DPRs by sequence number and originating VIU. In conjunction with specific protocols, all DPRs are thus collected reliably, even though communication with a vehicle may be intermittent. Efficient use of WiFi bandwidth is made by avoiding the unnecessary collection of duplicate DPRs.
