Abstract: A method and apparatus are disclosed for determining the starting location and starting protocol of LAN data in a WAN frame. A list of offsets and a list of LAN protocols are maintained. For each offset in the offset list, the WAN frame is parsed beginning at the offset and each LAN protocol in the LAN protocol list is looked for, one at a time. If no LAN protocol is recognized to begin at this offset, the next offset in the offset list is chosen and all of the LAN protocols are tried once again beginning at the newly-chosen offset. This process is repeated until all of the LAN protocols are tried at all of the offsets, or until a LAN protocol is recognized. If a LAN protocol is recognized, the offset at which the protocol was recognized is reported, together with the identity of the LAN protocol that was recognized at the offset. If a LAN protocol is not recognized, an appropriate error message is reported.

Abstract: A method and apparatus for measuring quality of cooking or frying oil in situ is provided. The oil quality sensor apparatus utilizes simultaneous monitoring of change in the capacitance and optical transmission of the oil in situ in the cooking or frying temperature range. The sensor monitors the chemical degradation as well as the sensory acceptance of the oil. A large, high surface area and multi-plated parallel plate capacitor is used to measure the capacitance to provide a reliable measure of concentration of total polar materials in the high polar region. A diode laser operating at a wavelength of 675 nm and photodetector are used to measure transmittance of the oil in situ with a microprocessor processing the transmittance and capacitance data. The sensor is programmed to indicate oil is to be replaced if either a preset minimum safe percent transmittance threshold is exceeded based on the transmission measurement or a change in capacitance exceeds a preset threshold value.
