Timer Advantages

Posted on

The benefits and increased comfort of the versatile helpers which person would also be not enthusiastic, the morning coffee is already prepared, when you stand up, although there is no one actually, which has equipped the coffee machine? If in the evening the electronics go to the light at a certain time in the apartment, to deter burglars, even though no one is at home? Or would be one not happy in the cold season when the heating comes on automatically? Now timers provide this increased comfort in many households. The forerunner of the electric timer was the mechanical clock, which raises the hitting of a church bell or the ringing of an alarm clock at a certain time and in a direct way with the movement of a mechanical watch is connected. Here, a switch is activated by the movement, after the position of the switch by hand has been preset, such as in a conventional alarm clock. Nowadays, there are digital timers, which are frequently closed between socket and consumer. In this way, you can each connect every electronic device and program the timer so that it releases the power supply to the consumer, so the unit goes into operation.

In this case, the actual contactor is a relay. A built-in digital clock at the programmed time sends voltage to the relay. The counter allows for the switching on and off according to the defined time interval. Often, the used watches are quartz watches, whose Geber is a uniform oscillating quartz plates. There are also radio time switches, the the current time from a central station of time signal received by radio and thus alone adjust. Timers are used when the street lights are dimmed in the late night. Also the classic traffic light systems are equipped with these timers and adapted to the respective traffic conditions. The light on the stairs with the aid of these timers is controlled also in apartment buildings. Time switches through the automation of various processes contribute to the increased comfort of the people.

Miniaturized JEN COLOR color sensor module for backlighting applications Jena the MAZeT GmbH, product and Designhaus for colour – and Spektralsensorik, expanded its extensive range of highly accurate solutions for the control of LEDs, as well as special developments for the light control. The leading provider of true color sensors, and sensor modules for the first time shows the newly developed true color sensor TIAM3 with integrated signal processing. He distinguishes itself by 4 programmable amplifier channels and the true color sensor. Compared to the ancestor type TIAM2 is the TIAM3 in a flat 33% housing. The low overall height and the integrated signal processing establish optimal conditions for use for the RGB-LED backlighting in flat panel displays. In contrast to color sensors with polymer filter coatings, the TIAM3 is characterized by a high long term stability of the spectral filter properties and low temperature sensitivity. The spectral properties of the filter curves are optimally tailored to the requirements of an eye-specific LED color control. The sum of the properties of the smallest size, spectral characteristics and signal processing recommend this component for precision-controlled backlights of flat screens. In particular displays for photo and image editing, for medical diagnostic imaging or for high-quality multimedia displays require these properties of the backlight.

Piezoantriebs

The focusing speed is the most critical factor in the screening, because often the effects to be examined are time-dependent. Also the irradiation of fluorescent tracer is toxic to cells, and in an automated handling process, the requirement is for high throughput of samples. Depth effects can be observed fine adjustment of the focus for the three-dimensional imaging in this way. The adjustment of the focus on different levels of virtually cut the sample. The piezo drive allows you as a keen eye on operations within the sample. Responsiveness and settling times are again in the range of few milliseconds. A measurement is possible due to the high speed stability during movement.

The confocal microscopy is used to generate a three-dimensional image of a sample. Here, images of the sample in different focal planes are created and assembled by software. The entitlement to the resolution of the Z drive to adjust the focal plane are very high here, positioning accuracies in the range of a few 10 nanometers are required. Classic stepper motor drives are neither fast nor accurate enough here. PIFOC Piezo Z-drives: The imaging optics or the trial must be moved for lens, lens turret or sample holder for focus tasks and the adjustment of the focal plane. PIFOC Z-drives for the lens can be built very small and stiff. You therefore have faster response times, better governance and are accurate at large travel paths.

Another advantage is that the sample does not move during focusing and thus despite the quick response of the Piezos, remains undisturbed. The movement of the sample is however, not weakening the image in phase contrast microscopy (differential interference contrast microscopy, DIC). Also, Piezo-Z-drives for the sample due to their small size can be integrated in the motorized XY sample scanner, the as a system component of the microscope there is already common. The adaptation effort can thus minimized, lenses can be used flexibly. Customized PIFOC lens drives but move as the entire revolver or move a DIC Prism with highly specialised applications require appropriate solutions. Many microscope manufacturers already offer a wide range of equipment and accessories for the various microscopy techniques system integration. Sample scanner in the XY include level and Z rough shoots for the imaging optics that achieve accuracies in the range of microns with the usual stepper drives. Piezobasierte Z-drives for fast focusing are, however, rare to find standard accessories on the microscope manufacturers; These must usually be retrofitted. The task of the manufacturer of piezo drive systems is also to adapt lens Positioners for lens sizes. Piezo Z-drives for samples of physics instruments (PI) with travel strokes from 0.1 to 0.5 mm Watch XY-scanner without adapter in March-houses. Sample holder can be used Z adjuster for slides and micro titer plates of March homes directly in the piezo. The still low overall height of the built-in XY-Z system allows the use under common microscopes. Also the control of the Piezoantriebs must be easily integrated. This is a fast control via analogue signals. Alternative commanding via digital interfaces is implemented via software drivers. Piezo-Z-drives represent a possibility of easy-to-integrate, to adjust lens and sample relatively to each other. While a resolution can be achieved by a few nanometers for travel paths of up to 0.5 mm. The response times are just a few milliseconds.
