An antenna positioning system includes an outdoor unit with a rotating antenna driven by a motor, and an indoor unit connected to the outdoor unit via a communications link, such as a cable or a wireless link, that enables the indoor unit to control the outdoor unit. On startup, the processor of the indoor unit directs the antenna to search for available signals. The resulting signal information is stored and displayed on a user interface on the indoor unit. The user can then select a desired signal and the processor of the indoor unit will automatically rotate the antenna to the appropriate angular position. Both the search procedure and repositioning of the antenna rely on accurate calibration of the antenna's angular velocity to determine the antenna's angular position, rather than relying on a position sensor.

A device is configured to control a transition timing of a switching DC/DC converter for providing power to a load device. The load device has a first operational phase that is sensitive to external noise and a second operational phase that is immune to the external noise. The device includes an input terminal coupled to an external device to receive a start signal of the first operational phase for the load device. The device also includes control circuitry configured to, responsive to the start signal, control a transition frequency of the DC/DC converter to avoid transitioning an output of the switching DC/DC converter during the first operational phase.

The present invention relates to the technical field of photographic apparatuses, and in particular, to a locking assembly, a driving-type locking mechanism, a telescopic supporting leg, and a tripod. The locking assembly includes a fixing base and a rotating shaft member, an abutting component is fixedly sleeved on a periphery of the rotating shaft member, and an elastic component and a movable component are disposed on the periphery of the rotating shaft member. The driving-type locking mechanism includes a driving component and the locking assembly. The telescopic supporting leg includes the driving-type locking mechanism, an upper sleeve, and a lower sleeve. The tripod includes a tripod base, an operating component, and three telescopic supporting legs. According to the present invention, a transmission member is not needed to provide locking force or locking torque for the locking assembly.

System and methods for processing a substrate using a reactor with multiple heating zones and control of said heating zones using a common terminal shared between two power supplies are provided. The reactor includes a heater assembly for supporting the substrate and a showerhead for supplying process gases into the reactor. An inner heater and an outer heater are integrated in the heater assembly. An inner power supply has a positive terminal connected to a first end of the inner heater and a negative terminal is connected to a second end of the inner heater that is coupled to a common terminal. An outer power supply has a positive terminal connected to a first end of the outer heater and a negative terminal connected to a second end of the outer heater that is coupled to the common terminal. A common-terminal heater module is configured to receive a measured temperature that is proximate to the inner heater. A desired temperature setting is received and a servo control law is processed to identify a direct control setting of an inner voltage of the inner power supply and an open-loop control setting of an outer voltage for the outer power supply. The outer voltage is defined as a ratio of the inner voltage.
