Abstract: The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.

Abstract: A conical workpiece length measurement method is provided. Two laser displacement sensors are symmetrically arranged at opposite sides of a to-be-measured conical workpiece or a tooling loaded with the to-be-measured conical workpiece. Distance X0 from each displacement sensor to a bottom plane of the to-be-measured conical workpiece is calibrated. An elongated base plate is arranged at a tip of the to-be-measured conical workpiece, and the two displacement sensors measure their respective distances to the base plate. The total length of the to-be-measured conical workpiece is calculated as follows: X=X0+(X1+X2)/2, where X1 represents distance from one of the two displacement sensors to the base plate, and X2 represents distance from the other of the two displacement sensors to the base plate. Factors influencing the length measurement include calibration of the fixed length, measurement accuracy of the displacement sensor and a tilt error of the base plate.

Abstract: According to one or more embodiments of the technical solutions described herein, a control system in a motor vehicle that includes an internal combustion engine includes an oxygen sensor, and an oxygen sensor diagnosis module to diagnose the oxygen sensor. The oxygen sensor diagnosis includes performing an intrusive rich-to-lean diagnostic for the oxygen sensor, and detecting a lean-to-rich diagnostic event. In response, the diagnosis includes performing a passive lean-to-rich diagnostic for the oxygen sensor, the lean-to-rich diagnostic event comprising a fuel enrichment.

Abstract: A system includes an ultra-capacitor and battery system comprising a battery, a DC-DC converter, and an ultra-capacitor. An auto stop/start module is configured to perform an auto stop event of an engine of a vehicle and an auto start event of the engine of the vehicle based on operating parameters while an ignition is ON. A voltage monitoring module is configured to, in response to a request for an auto start event, selectively discharge the ultra-capacitor during cranking for the auto start event, accumulate a plurality of voltage delta values while the ultra-capacitor discharges during the cranking, and selectively disable the auto stop/start module based on the plurality of voltage delta values.

Abstract: A system includes an ultra-capacitor and battery system comprising a battery, an ultra-capacitor, a DC-DC converter, a first temperature sensor to sense a battery temperature, a second temperature sensor to sense an ultra-capacitor temperature and a third temperature sensor to sense a DC-DC converter temperature. An auto stop/start module is configured to selectively stop and restart an engine of a vehicle while an ignition system is ON based on operating parameters. A temperature sensing module communicates with the auto stop/start module and is configured to determine differences between temperatures sensed by the first sensor, the second sensor and the third sensor and to selectively disable the auto stop/start module based on the differences.

Abstract: A control system for a vehicle includes a first vehicle system including a plurality of components and a controller. The controller monitors diagnostic data for the plurality of components of the first vehicle system and outputs a two-state status indicator for each of the components of the first vehicle system. States of the two-state status indicator include a failing state and a not failing state. A control module is configured to receive the two-state status indicator and the diagnostic data from the first vehicle system and to convert the two-state status indicator into a three-state status indicator. The three-state status indicator includes a pass state, a fail state and an indeterminate state. The control module is further configured to alter an engine operating parameter based on the three-state status indicator.

Abstract: A method of maintaining a substantially stable engine speed after a garage shift of an automatic transmission includes identifying a moment when a load from the automatic transmission is applied to an engine via a torque converter during the garage shift based on a first turbine speed change with respect to a reference engine speed change and a second turbine speed change with respect to an actual engine speed change. The method further includes generating a feed forward torque command based on a turbine speed decrement after identifying the moment when the load from the automatic transmission is applied to the engine, and controlling the engine based on the feed forward torque command to maintain a substantially stable engine speed after the garage shift.
