Abstract: Disclosed herein is an apparatus. The apparatus includes a sensor head section, a base section, a telescoping section, and an electronic component. The base section is connected to the sensor head section. The telescoping section includes a first end and a second end. The telescoping section is connected to the base section. The electronic component is proximate the first end of the telescoping section. The electronic component is protected from making contact with high current, electrically conductive battery elements and configured to sense battery parameters.

Abstract: A method and a system are disclosed to at least specify, document and prototype a device, such as a gauge, having specific user interface elements to meet individual customer/market needs. The method includes displaying, with a graphical user interface, an image of a customer-selected gauge type; enabling the customer to specify, with the graphical user interface, individual ones of a plurality of gauge parameters in a self-documenting fashion; in response to a selection of at least one type of gauge parameter, updating the displayed image to correspond to the selected gauge parameter; and developing at least one prototype gauge for the customer based on the selected gauge parameters and the self-documentation. In the preferred embodiment the method also includes manufacturing gauges based on the selected gauge parameters and the self-documentation.

Abstract: In a preferred embodiment, an engine oil change indicator system, including: a combination engine oil pressure sensor and engine oil temperature sensor connected to a port on the engine to which port is normally connected an oil pressure switch; and a microprocessor connected to receive inputs from the combination engine oil pressure sensor and engine oil temperature sensor and to cause a low engine oil pressure warning light to be illuminated when the microprocessor has calculated from the inputs that the engine oil should be changed.
