Abstract: A table driving system of a patient table is disclosed. The table driving system comprises one or more carriage unit capable of moving along a base member of the patient table. The patient table comprises a table top, the base member and a table lifting unit connected to the base members and a bottom portion of the table top. The table driving system also includes one or more actuating units. An actuating unit has its ends operatively connected to a carriage unit and the table lifting unit. The actuating unit is configured to retractably extend to operate the table lifting unit for the table top to attain a raised configuration and a lowered configuration. The carriage unit is configured to move along the base member to facilitate the operation of the actuating unit.

Abstract: A heat exchanger for controlling temperature of electrical or electronic components has at least one flat tube with an inlet port and outlet port. A coolant entering through the inlet port passes through multiple heat sinks located within the flat tube before exiting through the outlet port. The heat exchanger has a first heat sink coupled to the flat plate with multiple fins arranged based on a first fin configuration, a second heat sink coupled to the flat plate with multiple fins arranged based on a second fin configuration, and at least one coupling device. The heat sinks are arranged based on a position of one or more components mounted on the flat tube such that the number of heat sink fins is proportional to heating characteristics of the components mounted on the tube.
