Title: Method and apparatus for calibrating a vehicle compass system
Inventor: SPITZ ROBERT F
IPC: G01C17/38
Filed: 1994-03-29
Granted: 1997-09-30
Abstract: A vehicle compass system that is adapted to be calibrated in the assembly plant during final assembly of the vehicle. In particular, two factory calibration modes are disclosed: an automatic factory calibration mode wherein the calibration sequence is automatically initiated upon the occurrence of a uniquely definable event on the assembly line, and a manual factory calibration mode wherein a calibration button sequence is actuated at a specified location on the assembly line. In addition, an automatic adaptive calibration process is disclosed which continuously updates the calibration constants each time valid new heading data is obtained. In particular, heading vectors for the tour main N, S, E, and W heading directions are calculated and stored in memory when the system is initially calibrated. Thereafter, whenever new heading direction data is obtained, the value of the new heading vector is used to update the value of the closest of the four main heading vectors. A new center calculation is also performed using the updated values and if the result is outside a tolerance window, the calibration constants are changed accordingly.

Abstract: The properties of two recombinant human IL-2 analogues with mutations at Arginine 38 (.fwdarw. Alanine) and Phenylalanine 42 (.fwdarw. Lysine) were analyzed and compared to those of native IL-2. These analogues were found to maintain their ability to bind to the intermediate IL-2 receptor, p75, while binding only minimally to the high affinity p55 + p75 receptor complex. The analogues also maintained the ability to stimulate peripheral blood mononuclear cells to generate lymphokine activated killing (LAK). However, IL-1.beta. and TNF-.alpha. secretions were significantly reduced in response to the analogues, as compared to the native IL-2 molecule. These analogues are therefore potentially valuable low-toxicity alternatives to IL-2 in human immunotherapy and adoptive immunotherapy treatment strategies.

Abstract: A dynamic strobe compensation control for a battery powered barcode printer varies the strobe time for the thermal printhead of the printer during the printing of a line of data to compensate for internal resistance losses in the thermal printhead. The control varies the strobe time based upon the measured voltage of the battery powering the printhead when the battery is not loaded by the thermal printhead and when the battery is load by the thermal printhead. The print quality is thus maintained across the width of a line of print data as well as over multiple lines of print data.
