Abstract: A computer-implemented method of controlling a patient positioning apparatus for a radiotherapy system. The patient positioning apparatus comprises a tiltable patient support apparatus. The method comprises receiving a reference position of the patient support apparatus, and determining a position adjustment signal for controlling at least one actuator to adjust the position of the patient positioning apparatus from a current position to the reference position based on a parameter dependent on a physical characteristic of a patient.

Abstract: A subject support apparatus (1400, 1600) for a radiation therapy device. A subject support apparatus (1400) comprises a subject support (1410), a subject support receiving portion (1420) and a deformable guide (1418). The subject support (1410) is configured to tilt relative to the subject support receiving portion (1420). The deformable guide (1418) comprises a first face (1431) and a second face (1433), wherein, throughout a range of tilt configurations, the first face (1431) is arranged to be in contact, at least in part, with a longitudinal side wall of the subject support (1410).

Abstract: A stamping machine for mounting a retention frame of heat sink (510) to a motherboard (500) includes a machine body (100), an adjusting device (200), and a controlling unit (300). The machine body comprises a support plane (110) and a stamping arm (120) extending upwardly from the support plane. A plurality of adjusting positioning blocks (112) is provided on the support plane for fittingly positioning the motherboard. A stamping assembly (130) is positioned at a forepart of the stamping arm comprises a cylinder (140), a stamping block (150) moveably connected to the cylinder, and a base portion (114) attached on the support plane corresponding to the stamping block. A plurality of stamping posts (170) extends from the stamping block and a plurality of retractable pressing pins (180) depends from the stamping block. A resilient member (190) is disposed around each of the pressing pins.
