Abstract:
A personal formulation device for mixing and dispensing customized formulations from ingredient reservoirs carried by the device. The device may include a plurality of miniaturized progressive pumps with a flexible coupling between the motor and the pump. The coupling may include a spring (40). The device may include a spacer sleeve (62) having an internal diameter tapered to closely follow the motion envelope of the spring (40). Each pump may include a retainer (60) that is threaded into the interior of the pump body (52) to retain the spacer sleeve (62) and the drive end (120) of the rotor (34). Each pump may include a stator with an integrated flange seal (36). The flange seal (36) may extend around the circumference of the stator and be sandwiched between portions of the pump body (52). The stator may have a noncircular shape that keys the stator within the pump body. The pump may include an optical metering system.
Abstract:
The present application relates to a flight mill comprising at least one twisted wire as the flight arm and methods of using the aforementioned flight mill. When compared to conventional flight arms, twisted wire flight arms have the advantages of being light, flexible, have a high tensile strength, are durable, have low kinetic friction and are cost effective to manufacture. The arm can be made from a single twisted wire or from a twisted pair of wires.

Abstract:
An absolute value encoder for sensing the number of revolutions, wherein an A-phase/B-phase generating section (610) generates A-phase/B-phase one-period pulse signals the phases of which are 90 degrees different from each other within one revolution of the shaft on the basis of the light passing through a slit rotating together with the shaft. When an A-phase/B-phase status sensing section (640) senses a change of the pulse signals, a clock generating section (66) switches the clock frequency.
Abstract:
A measurement and control system for controlling system (200) functions as a function of rotational parameters of a rotating device (102) and includes a plurality of interval markers (110) distributed around the periphery of the rotating device and fixed relative to the device support (104). The measurement and control system (200) also includes a plurality of sensors (112, 114, 202) attached to the periphery of the rotating device, fixed relative to the rotating device so as to be in close proximity to the interval markers. Measurements from sensors attached to different locations on the rotating device are combined so as to mitigate variations in angular speed of the device. Measured rotational parameters are used to predict, via linear interpolation, angular positions of the device between those positions measured by the sensors.
Abstract:
A vehicle display system (1) comprises a stationary detection means (34) and an indicator (2), which form a stationary vehicle detection means being operative to produce an indicator signal which is indicative of the vehicle being stationary. A vehicle display system (1) comprises a vehicle deceleration detection means (32) and an indicator (2), the detection means being operative to measure the magnitude of deceleration of a vehicle and generate a signal to drive the indicator and thereby generate a display indicative of the magnitude of vehicle deceleration, the vehicle deceleration detection means being independent of the vehicle braking system. The indicator can be an array of lamps (10 to 17) and the stationary vehicle indicator signal an animate display whereby the lamps are turned on and off. Additionally, there is provided a ranging device (60) which can be used to detect a trailing vehicle within a predetermined distance of the vehicle comprising the ranging device. The ranging device (60) may be used to initiate a change of the display generated by the vehicle display system (1).

Abstract:
A method and apparatus are described for forming a pattern comprising one or more markings on a substrate (6). The method comprises the step of forming each marking by locally heating the substrate (6), for example using a fibre laser (2). A step is also performed of monitoring the temperature of the substrate, e.g. using a temperature sensor (10), whilst each marking is being formed. The method may be used to form a magnetic encoder scale on a stainless steel substrate having a high content of martensitic material. The local heating causes the martensitic material to be transformed into austenitic material. An encoder scale made using the method is also described.
