Abstract: A chair assembly has a base frame, a pivot frame, a backrest frame, a seat frame and a backrest-adjusting device. The pivot frame is mounted pivotally on the base frame. The backrest frame is mounted securely on the pivot frame. The backrest-adjusting device is mounted between the base frame and the pivot frame and has a torsion spring biasing the pivot frame and the backrest frame to pivot forward. The backrest-adjusting device tightens or loosens the torsion spring to change the resilient force provided to the backrest frame against users' back. Therefore, the chair assembly adapts to differ users well.

Abstract: A treadmill roller structure comprises a motor, a gear set and a case. The motor is an out-runner motor. The power output section of the motor rotates about stationary spindle. The rotary power output section is engaged to the gear set, while the gear set is in turn engaged to the case, thus allowing the case to rotate relatively to the spindle of the motor as well. The roller structure does not require a driving belt to transfer power from the motor to the roller, thus reduces the power loss due to frictional force during power transfer through belt driving, which enhances the performance of the motor and offers a space-saving feature. In addition, the instant disclosure also provides a treadmill.

A second threaded portion is formed on the inner surface of the cover for mating to the first threaded portion on the hollow cylinder. The filtering medium is held in between the cover and the hollow cylinder and covers the thru hole. A filter pad is further included to provide additional functions. Accordingly, the nasal filter offers air purification and doe not cover the mouth.

Abstract: This invention relates to a function switch on handle of motorcycle, in which a light transmissive zone is formed on the housing thereof. A light emitting source is provided at the interior of the function switch which is coupled to the switches for small light and large light. In this manner, when driver turns on small light or large light, the light emitting source can also be energized to radiate light and the light beam emitted from the light emitting source can be projected out through the light transmissive zone of the housing so as to highlight the pattern of the light transmissive zone.

Abstract: A system and method are provided for adaptively controlling timing in SAR ADC of a sampled analog signal within a conversion period. A state machine maintains a set of SAR states including a sampling state and a plurality of bit conversion states. A reference generator generates a quantization level reference for each of the bit conversion states within a parametric settling time thereof. A comparator compares the sampled analog signal with the quantization level reference over a parametric propagation time for determining a hit value for each hit conversion state. A clock generator adaptively defines signals for clocking the state machine and comparator for each SAR state, thereby adaptively delaying bit determination in each bit conversion state by an integration period not less than the settling time, while adaptively delaying quantization level reference generation for a next bit conversion state by a regeneration period not less than the propagation time.

Abstract: A monitor system for monitoring riverbed elevation changes at bridge piers is revealed. The monitor system includes a container, a rail, a holder, a photographic unit, a processor and a transmission unit. The container is disposed at a pier under the water and the rail is mounted in the container. The holder is arranged at the rail and is moved on the rail. The photographic unit is disposed on the holder to capture a monitor image of a riverbed under the water. As to the processor, it processes the monitor image so as to learn elevation change of the riverbed under the water. By the transmission unit, the riverbed elevation change is sent to a remote monitor unit so as to get the riverbed elevation according to the riverbed elevation change. Thus the riverbed elevation change at the bridge pier is monitored in real time.

Abstract: The present invention discloses a dual rotating dewater bucket and a mop. The dewater bucket includes a freely-rotating dewater basket and a spindle member for receiving a cotton strip disc of the mop. With a passive dual rotating mechanism together with an active rotating mop, a cotton strip disc is placed in the spindle member and rotated, so that the cotton strips of the mop are stirred and spun towards the wavy bucket wall to remove dirt effectively, and then a dewater basket disposed in the same bucket body is used for spinning water absorbed by the cotton strips by a centrifugal force, similar to a washing machine or a dewatering machine to achieve both functions of cleaning and dewatering the mop without the need of a stepping action and provide a convenient and user-friendly operation and a safe application.
