Abstract: A radio frequency (RF) tamper detector of an electronic device can offer improved chassis intrusion monitoring to protect the device from software and hardware-based tampering. The tamper detector can monitor RF noise levels in a first frequency band and in a second frequency band to calculate an RF noise level moving average for each frequency band. If the moving averages in both frequency bands exceed a RF noise threshold, the tamper detector can set a cover removal flag to indicate that a cover of the device housing has been removed. The tamper detector can cause the electronic device to lock or disable a system BIOS when cover removal is detected. Additionally, the electronic device can notify remote monitoring systems (e.g., operated by an IT administrator or warranty support center) to receive additional instructions to secure the device.

Abstract: An overlay error measurement method includes disposing a lower-layer pattern over a substrate that includes disposing a first pattern having a first plurality of first sub-patterns extending in a first interval along a first direction and being arranged with a first pitch in a second direction crossing the first direction. The method includes disposing a second pattern having a second plurality of second sub-patterns extending in a second interval along the first direction and being arranged with a second pitch, smaller than the first pitch, in the second direction crossing the first direction. The second sub-patterns are disposed interleaved between the first sub-patterns. The method includes disposing an upper-layer pattern including a third pattern having the first pitch and at least partially overlapping with the lower-layer pattern over the lower-layer pattern and determining an overlay error between the lower-layer pattern and the upper-layer pattern.

Abstract: A sprinkler water flow switching device is assembled in a movable seat of the water sprinkler with a partition dividing into an impeller chamber and a gear chamber. The partition is provided with a first water channel and a second water channel for directing water from the gear chamber to the impeller chamber, so as to control the direction of rotation of the impeller in the impeller chamber. The water flow switching device includes a projection member, a seesaw plate and a driving lever in the gear chamber; the driving lever can oscillate and actuate the seesaw plate to move on the projection member, then the seesaw plate can move as a seesaw to selectively close the water inlet of the first water channel or the second water channel, thereby changing the rotation direction of the impeller and the water spray direction.

Abstract: A joint assembly is connected to a hose assembly. The hose assembly includes a hose in a sleeve. The joint assembly includes an internal joint and an external joint. The internal joint includes an external thread, a shank at an end, and an annular ridge on the shank. The external joint includes an internal thread, a connective portion at an end, a shank at another end, and a conical internal face. The shank of the external joint is inserted in the sleeve. The external joint receives the hose. The shank of the internal joint is inserted in the hose. The external thread of the internal joint is engaged with the internal thread of the external joint to cause the annular ridge of the internal joint to press the hose against the conical internal face of the external joint.

Abstract: A sprinkler includes a nozzle-swinging apparatus including a movable base and a current-switching unit. The movable base includes a partition between two chambers that contain a leafed wheel and a gear train. The partition includes two channels between the chambers. The current-switching unit includes two tabs, two connectors, a valve and a switch. The tabs extend toward the connectors in one of the chambers. The valve includes two pivots each of which extends in a gap between one of the tabs and one of the connectors. The switch includes a valve-moving element for grabbing the valve and a lever including a first section extending out of the movable base and a second section extending in the movable base. The first section of the lever is operable to pivot the second section of the lever so that the valve-moving element causes the valve to close one of the channels.

Abstract: A faucet is provided with a diverter. The diverter includes a body, an inlet module, two outlet modules and a control module. The inlet module is connected to the body. The outlet module is connected to the body. The control module is connected to the body. The control module is operable to switch between directions and modes for supply water. Each of the modules includes a small number of components. The diverter can be taken apart for repair because the modules are not interconnected by ultrasonic welding.

Abstract: An extensible hose includes a hose, a protective tube and a sheath. The hose is expansible in a radial manner and extensible in an axial manner. The protective tube is expansible in a radial manner and extensible in an axial manner, wherein the protective tube wraps the hose. The sheath wraps the protective tube. The sheath includes elastic warps and non-elastic weft. The elastic warps extend parallel to the protective tube. The non-elastic wefts sorted into a first group and a second group. The non-elastic wefts in the first group extend around the elastic warps in a right-hand helical manner and in an S-shaped manner. The non-elastic wefts in the second group extend around the elastic warps in a left-hand helical manner and in an S-shaped manner.
