Abstract: A system of performing boundary scan test on pin through test point and a method thereof are disclosed. When an under-test pin of a target connector is determined to be unable to perform a boundary scan test, a test point connected to and closest to the under-test pin is searched, a test signal is transmitted to a target connector, a result signal from the target connector in response to the test signal is received, an expected result and the result signal are compared to generate a test result, so that a boundary scan function can be applied to test a connector of a computer product, to achieve the technical effect of providing a better test range and a better test coverage to improve test efficiency and reduce test cost, compared to conventional boundary scan test.

Abstract: A method and system for obtaining wire information, includes a RFID tag, a RFID reader, and a data center. The RFID tact obtains the sensing information of the wire and transmits the sensing information and identification information of the RFID tag. The RFID reader transmits high-frequency electromagnetic waves to trigger the RFID tact and transmits and receives sensing information and identification information sent by the RFID tag. The data center is communicatively connected with the RFID reader and determines the type of the received sensing information based on the received sensing information and identification information for data analysis.

Abstract: A strain wave gearing has a wave generator provided with a rigid plug and a wave bearing. The wave bearing is of a deep groove bearing type and is mounted on an elliptical outer circumferential surface of the rigid plug, whereby outer race and inner race thereof are flexed into an elliptical shape. Where D is a ball diameter of the balls, Ro is a raceway-surface radius of the outer race, Ri is a raceway-surface radius of the inner race, Ro/D is an outer-race conformity, and Ri/D is an inner-race conformity, the outer-race conformity Ro/D is greater than the inner-race conformity Ri/D. The friction torque of the wave bearing can be reduced while maintaining the practical service life thereof to be the same level as in a conventional one.

Abstract: A surgical clip applier (100) includes a handle assembly (110) having a housing (118), a trigger (114), and an advancing mechanism supported in the housing (118) and being actuatable by the trigger (114). An elongated tube assembly (200) extends from the housing (118). A first shaft (202) is slidably disposed within the elongated tube assembly (200) and defines a surface portion (203). A second shaft (215) is disposed through an outer surface of the elongated tube assembly (200) and is in operative engagement with the surface portion (203) of the first shaft (202). Upon actuating the advancing mechanism, the first shaft (202) moves distally within the elongated tube assembly (200) relative to the second shaft (215) such that the surface portion (203) of the first shaft (202) traverses the second shaft (215) to produce at least one of an audible or tactile feedback.

Abstract: An externally toothed gear of a dual-type strain wave gearing is provided with first and second external teeth having different teeth numbers, and a gap formed between these teeth as a cutter clearance area for tooth cutters. The maximum width L1 of the gap is 0.1 to 0.3 times the width L of the externally toothed gear. The depth from the tooth top land of the first external teeth to the deepest part of the gap is 0.9 to 1.3 times the depth of the first external teeth, and the depth from the tooth top land of the second external teeth to the deepest part of the gap is 0.9 to 1.3 times the depth of the second external teeth. The tooth bottom fatigue strength of the externally toothed gear provided with differing numbers of first and second external teeth is increased.

Abstract: In a silk hat-shaped external gear for a strain wave gearing, t(A)>t(C)>t(D)>t(B) is satisfied, where the thicknesses of the inner circumferential end (A), the middle part (B) and the outer circumferential end (C) of the diaphragm body portion of a diaphragm are t(A), t(B) and t(C), and where the thickness of the barrel-side end part (D) of the curved portion of the diaphragm is t(D). With reference to the thickness of the middle part (B), the thickness of the inner circumferential end (A) of the diaphragm is set so as to be thicker than conventional silk hat-shaped external gears. It is possible to realize an externally toothed gear capable of preventing diaphragm rupture due to thrust force at high load torque and having high fatigue strength.

Abstract: A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.
