| 7002114 | Methods and apparatus for a variable resistor configured to compensate for non-linearities in a heating element circuit An improved variable resistor at least partially compensates for non-linearities in an electrical circuit containing a heating element, for example, a thin-film heating element. A controllable heater includes a heating element, a voltage source (for example, a stand... | 02/21/2006 |
| 6836207 | Strip conductor having an additional layer in a curved section A strip conductor comprises a first layer with at least one curved section. At least one region of the curved section provided with an additional layer having a smaller resistivity than the first layer. The at least one region is constructed such that resistance on ... | 12/28/2004 |
| 6342829 | Accelerator opening degree sensor A sensor comprises a linear region (variable region) in which the output voltage is changed in proportion to the accelerator opening degree, and a stepped region (invariable region) in which the output voltage is not changed with respect to the accelerato... | 01/29/2002 |
