Abstract: Both before and after a surprise clock stop, the apparatus and method of various embodiments supplies a stable and continuous clock to a memory module with a unique arrangement of circuit components, including a clock detector circuit, a clock-smoothing circuit, and one or more PLLs. Upon detection of a stopped host clock, a first PLL seamlessly switches to an alternate reference clock from an on-board crystal oscillator. A clock smoothing circuit allows the first PLL to maintain a steady phase and frequency without inducing glitches or period excursions greater than the natural jitter of the locked PLL; one or more optional downstream PLLs may drive additional clock domains.

Abstract: An auxiliary handle of a scissors for scissoring high branches, including a first casing and a second casing which are symmetrical to each other. The first and second casings are pivotally connected with each other at one end to define therebetween a receptacle. An elongated tube of the scissors is passed through the receptacle. A cap member is tightened on the other end of the first and second casings, whereby the first and second casings can tightly clamp the elongated tube to fix the auxiliary handle on the elongated tube.

Abstract: A urine bag for a male human has a pouch with an opening defined in the pouch, a fastener mounted around a periphery defining the opening, and an arcuate piece mounted between the arcuate piece and the periphery. The pouch is composed of a permeable layer, an absorbent layer, and a waterproof layer. The urine bag can be worn to collect urine from a user who does not have convenient access to a toilet, and the urine bag is disposable after use.

Abstract: This disclosure concerns a foldable saw. It includes a main body, an upper cover disposed on an upper wall of the main body, a lower cover disposed on a lower wall of the main body and a rear cover. This foldable saw has receptacles for receiving spare saw blades which can be taken out to replace the original one. Also, this foldable saw can store several saw blades and these saw blades can be changed for different purposes when it is needed.
