Abstract: The robotic arm operating system includes a control device, a plurality of joint devices and a brake release monitoring device. The control device is used to generate an operation instruction. The joint device is coupled to the control device. Each joint device includes a motor and a driver. The drivers of the joint devices receive the operation instruction to generate corresponding multiple unlocking signals. The unlocking signals are used to release a braking state of the motors of the corresponding joint devices. The brake release monitoring device is coupled to the control device and the joint devices, and includes a plurality of monitoring circuits. When one of the plurality of monitoring circuits does not receive the corresponding unlocking signal, the brake release monitoring device notifies the control device that the operation instruction is not allowed.

The second terminal is disposed on the base structure. The cover is disposed on the base structure and covers at least part of the first terminals and at least part of the second terminal.

Abstract: An optical module includes a micro spectrometer. The micro spectrometer includes an optical crystal, a lens, and a photosensitive assembly. The optical crystal is configured to receive detection light and covert the detection light into interference light. The optical crystal is surrounded by a sleeve, the sleeve configured to fix a position of the optical crystal. The lens is configured for receiving the interference light and focusing the interference light. The photosensitive assembly is configured for imaging the interference light into an interference image. The optical module further comprises a controller. The controller is electrically connected to the photosensitive assembly, and the controller is used to convert the interference image into light wavelength signals and light intensity signals.

Abstract: An electrical connector includes a metal shell, an insulative housing, a plurality of terminals retained in the insulative housing and a shutter. The metal shell defines a receiving space with a mating port. The insulative housing defines a mating portion extending forwardly and received in the receiving space. The mating portion defines two rows of passageways exposed on opposite surfaces thereof. The terminals include contact portions retained in the corresponding passageways of the mating portion. The shutter is located in the mating port of metal shell. The shutter is made of metal sheet and pivotally mounted to the shell. The shutter includes a main portion and a pair of shafts extending outwardly form two sides of one end of the main portion.

Abstract: An electrical connector assembly includes an insulative base and a complimentary connector assembled therewith along an up-to-down direction instead of a left-to-right direction. Thus, a small assembly space will be achieved compared to the prior art.

Abstract: An electrical connector assembly includes an upper insulative base and a lower insulative base discrete from each other, and assembled therewith along an up-to-down direction instead of a left-to-right direction. Thus, a small assembly space will be achieved compared to the prior art.

Abstract: A fan-out pattern having two or more fan-out sections is implemented between a driver IC and a display for reducing or eliminating the pathlength differences among the electrical conductors in the fan-out pattern. As such, some of the conductors between the driver IC and the display can have two or more zigzag swath widths. In a fan-out pattern having two fan-out sections, a first fan-out section widens the spacing, SI, between two adjacent conductors at the IC side to an intermediate spacing, SM, and a second fan-out section further widens the intermediate spacing SM to the spacing, SP, at the display side. With two fan-out sections, the first zigzag extension is implemented in some conductors between the IC side and the first fan-out section, and the second zigzag extension is implemented in some conductors between the first fan-out section and the second fan-out section.
