A sprinkler includes an outer housing having a lower end connectable to a source of pressurized water and a riser that is vertically reciprocable within the outer housing between extended and retracted positions when the source of pressurized water is turned ON and OFF. A nozzle is mounted at an upper end of the riser for rotation about a vertical axis. A Pelton turbine is mounted inside the riser for rotation about a horizontal axis, as distinguished from a vertical axis. A drive mechanism connects the turbine to the nozzle so that when the source of pressurized water is turned ON the resulting rotation of the turbine by the pressurized water will rotate the nozzle. The turbine as well as a gear train reduction and a bevel gear reversing mechanism are assembled inside a self-contained clam-shell drive subassembly before being inserted into the riser.

A high efficiency power drive device enabling serial connection of LED lamps thereto, which includes a power source filter circuit, an AC to DC rectifier, a power factor correction circuit and an LED constant current drive circuit. The power factor correction circuit is utilized using the so-called transition mode technique to obtain voltage required by the LED lamps when serially connected, and current control is used to achieve a state whereby the current and voltage are in the same phase. A current control IC and an externally set resistor are further used to eliminate the need to adopt any CPU (central processing unit) while accurately directly controlling the output pulse width of PWM (Pulse Width Modulation).

In this invention, a new class of finite precision multilevel decoders for low-density parity-check (LDPC) codes is presented. These decoders are much lower in complexity compared to the standard belief propagation (BP) decoder. Messages utilized by these decoders are quantized to certain levels based on the number of bits allowed for representation in hardware. A message update function specifically defined as part of the invention, is used to determine the outgoing message at the variable node, and the simple min operation along with modulo 2 sum of signs is used at the check node. A general methodology is provided to obtain the multilevel decoders, which is based on reducing failures due to trapping sets and improving the guaranteed error-correction capability of a code. Hence these decoders improve the iterative decoding process on finite length graphs and have the potential to outperform the standard floating-point BP decoder in the error floor region. The description and apparatus of 3-bit decoders for column-weight three LDPC codes is also presented.

In the operating method, a touch action of an input device is sensed and a touch signal is generated by the fingerprint sensor unit. A fingerprint analysis and an action analysis are performed according to the touch signal to determine a finger category of the input device and an action information of the touch action. An operation corresponding to the finger category and the action information is executed.

By adoption of the above technical solution, the present invention has the following beneficial effects: the structure is reasonable, the parts and components of the color mixing machine are reduced without reducing and decreasing the functions of the color mixing machine.

A non powered, canine barking suppression device that can rapidly altering a dog's behavior so as to visibly reduce anxiousness and unwanted barking.

The device subjects the dog to random vibrations and audible tones generated by an enclosed tuning fork that is worn around the dog's neck. The tuning forks when struck, emit a selected frequency selected for a specific purpose and or specific breed of canine. This frequency lies between 0 and 200,000 Hz, which is the range of sound that has been shown that most canines can hear. Since it is non powered it is not prone to failure in wet or cold environments, is durable and inexpensive. The device has claims of additional therapeutic properties and the general physical structure has applications elsewhere, although the preferred embodiment and best mode are directed to stopping unnecessary barking.

A flexible light guide film having a light-adjusting structure in the form of a lenticular-like microstructure on the bottom side of the light guide film. The light guide film has a substrate layer supporting a layer light-adjusting structure, which is in the form of an array of longitudinal lenticular lenses laterally arranged in parallel. A prismatic-like microstructure may be provided on the top light emitting side of the light guide film. The light guide film is fabricated by a process involving coating/embossing of a roll of sheet material, in a roll-to-roll continuous process. Advantages includes significantly reducing the thickness of the light guide film, and the roll-to-roll fabrication process provides for more precise replication of the microstructures on the master mold or drum onto the surface of the light guide film, which in turn reduces the failure rate and manufacturing cost.

In a method of manufacturing an imprint substrate, a concave pattern, which is recessed, is formed on a top surface of the mold substrate. A light blocking layer is formed on the concave pattern and the top surface of the mold substrate. After bonding an adhesive substrate to the mold substrate such that the adhesive substrate faces the mold substrate, the adhesive substrate is separated from the mold substrate, so that the light blocking layer on the top surface is removed from the mold substrate. An imprint substrate having the light blocking layer only on the concave pattern is formed.

Disclosure herein is related to a system for testing wireless signals and a method provided for establishing the system. One of the objectives is to establish one new testing system while the method effectively reduces the unstable problem caused by hardware or environmental variations. The testing system measures intensity of the wireless signals outputted from a device-under-test. While compared to a test signals, it is determined if the signal intensities there-between are balanced. Accordingly, the hardware of system is required to be adjusted. After that, the wireless signals are compared with sample signals for determining whether or not the test results are stable among the different testing system. An attenuation value may be introduced to adjusting the test result. A new testing system is therefore established.

In this way, the mop yarns may be dewatered in a more convenient and safer way.
