Abstract: An apparatus for removing accumulated snow and/or ice from the undercarriage of a motor vehicle before it is parked in an indoor garage or parking lot includes a piping network with multiple jet/spray nozzles installed on the undercarriage and configured to direct nozzle sprays of pressurized heated antifreeze solution and nozzle jets of pressurized heated air to the perimeter areas of the undercarriage, including the wheel-wells, where snow/ice accumulation is most prevalent. Along with the network of nozzles, the undercarriage snow/ice removal apparatus includes a conductive and/or radiative heating grid covering the undercarriage perimeter areas to which the nozzle sprays and nozzle jets are directed. The undercarriage de-icing apparatus also includes multiple capacitive undercarriage icing sensors distributed throughout the de-icing areas.

Abstract: A method for using a telephone system, in order to replace the use of existing mail systems, for sending out certified or registered information. The receipt of such information is acknowledged and responded to by use of this method. The method involves initiating the call, recording the substance of certified or registered information, prompting a pre-recorded announcement as soon as the communication is made in order to advise the recipient that the call is being recorded along with the time and date of the call. After the announcement, the pre-recorded information is transmitted, a record is made of the response, if any, and a full record, including time and date is sent to the initiator of the call. Alternatively, the "certified" information is spoken by the initiator, rather than being pre-recorded.
