A ground equipment (10) and a satellite tracking method used therein are provided. The satellite tracking method is employed by the ground equipment (10) to maintain communication with a satellite via a best communication beam. The method utilizes the signal strength received from the satellite through a plurality of candidate beams neighboring the best communication beam to determine whether to replace the best communication beam with one of these candidate beams (S400 - S404). This approach achieves efficient tracking by avoiding the need to scan all quasi-communication beams. Furthermore, when the ground equipment switches to an incoming satellite (a second satellite operating in the same orbit), the satellite tracking method determines the communication beam to be used to initiate communication with that incoming satellite. This determination is made based on the angular change of the ground equipment's orientation, where the angular change is measured between the point of initiating communication with the current (first) satellite and the moment of satellite replacement.

In a circuit (3) a MOSFET (14) is used for protecting a load (18) against wrong polarity of a power source (11) for the circuit (3). A driver (15) for the MOSFET (14) is configured to generate a pre-defined voltage drop between source (141) and drain (142) of the MOSFET (14) at correct polarity of power source (11). If wrong polarity of power source (11) is detected, driver (15) sets MOSFET (14) into a state of high resistance between source (141) and drain (142). The pre-defined voltage drop at correct polarity is associated with a resistance between source (141) and drain (142) which makes detection of wrong polarity more reliable.

A sensor assembly (1) for detecting immersion of a vehicle (100) in water is disclosed. A structural element (10) of the vehicle (100) is used to hold the sensor assembly (1). At least the flexible and deformable volume (7) must be under water level so that an immersion in water can be detected. To measure a pressure increase the flexible and deformable volume (7) need to be in fluid communication with the least one sensor housing (2, 3).

A system (1) for memory preservation is disclosed. A liquid tight and gas-tight housing (10) formed by a bottom (11) and a cover (12). A reservoir (14) holds a phase changing material (15). At least one memory device (20) is placed in a liquid-tight enclosure (16) surrounded directly or indirectly by the phase changing material (15).

A diode (23) used for ensuring unidirectional current flow in a DC-DC boost converter (40) is also used for protecting a circuit (3) including the DC-DC boost converter (40) against wrong polarity of a power source (11) of the circuit (3). A further diode (26) in the DC-DC boost converter (40) protects a driver (24) and a reference voltage source (21) of the DC-DC boost converter (40) against wrong polarity of the power source (11) of the circuit (3).

A columnar resistor and a method of laser trimming for manufacturing the same are provided. The columnar resistor includes a resistance layer disposed on the surface of a columnar substrate and the resistive layer includes a resistance determining area, a first resistance adjustment area, and a second resistance adjustment area. The resistance determining area is configured to form a first laser-trimming line and achieve a first resistance value by a first laser-trimming. The first resistance adjustment area is configured to form a second laser-trimming line and achieve a second resistance value by a second laser-trimming. The resistance value is precisely adjusted by two laser-trimming processes of the resistive layer, thereby improving the stability of product manufacturing.

A manufacturing method of flattening resistor (1), comprising: - disposing a substrate (10); - forming by printing an electrode layer (20) on both ends of the substrate (10); - forming by trimming a tangential concave platform (50) by laser-cutting or grinding a surface of the electrode layer (20); - forming by sputtering a resistive layer (30) covering the tangential concave platform (50) of the electrode layer (20); and - forming by printing a protective layer (40) on the resistive layer (30). The application further discloses a flat resistor obtained by the method. The present disclosure solves the problems of increased impedance and abnormal product characteristics caused by improper jointing of the interface between the electrode layer and the resistive layer, which includes using laser-cutting or grinding to eliminate the step difference of the interface and process the discontinuous structure of the electrode layer after the electrode layer process is completed.

A high-temperature resistant resistor is provided and includes a substrate layer, a first surface electrode layer, and a second surface electrode layer. The first surface electrode layer is disposed on a first surface of the substrate layer, the resistance layer partially attaches the first electrode layer and the substrate layer, the second surface electrode layer is aligned with the first surface electrode layer, and attached on the first surface electrode layer and the resistance layer, so that the resistance layer is fixed between the first electrode layer and the second electrode layer. The first surface electrode layer, the resistance layer and the second surface electrode layer form a composite structure to suppress the change in resistance value of the high-temperature resistant resistor at high temperatures.

A camera assembly (10) for a driver monitoring system (1) is disclosed with glare protection. A cap (16) for at least one LED (20) is provided to define an opening (21) through which a light cone (27) exits. The cap (16) is defined by a pass-through section (17) connected to at least one first sidewall (18) and one second sidewall (19). The first sidewall (18) is higher than the second sidewall (19) and the first sidewall (18) positioned close to the lens (12) of the camera assembly (10).

An apparatus for use in an elongated shipping container for selectively carrying solid freight and bulk liquid freight comprising a frame fixedly secured to the elongated shipping container, the frame comprising at least: two side members and at least one end member connected to the side members, a collapsible liquid container removably connected to the frame, the container having a liquid impermeable outer liner and a liquid impermeable inner bladder arranged within the outer liner, a fluid conduit in fluid communication with the inner bladder and removably connected to the frame, and at least one baffle operatively arranged to removably secured to the frame and on top of the collapsible liquid container.
