Date Time Clock Widgets
When i found the Remote controls and the early mobile phones difficult to use. I felt i have to try to design user interface within a small footprint. This helped me innovate a Active or Dynamic GUI concept; as shown in the Ability to change the skins of the Audio Music player and Digital Alarm Clock. The metronome too see the other project in this profile. These were done around 2005-6-7. Both for elements on my site and gadgets.
Digital Alarm Clock Gadget - I also made a Virtual Web Gadget Alarm Clock Simulation that will demonstrate a Dynamic GUI in a Limited Facia Area.
Reduce the number of operations a user would do at achieve a purpose. Auto, Intuitive, Context Gui. When a Customer comes to buy Trousers, Take him to the Trouser Corner. Do not show Tuxedo option. The colors have good contrast and the text clearly visible.
A Highlighted reaction to user action. Tactile. Dynamic GUI, see in Gadgets above. GUI Elements appear only for that sequence of actions. No clutter. Menus if used, should not get stuck. Should not be fidgety, should not be menus at all if possible.
Wilhelm Westermann in Unna/Westphalia in 1948 created and established
WIMA Germany. They make High Technology, Specialized Passive
Components. These are Plastic film capacitors, Paper capacitors and
The capacitors that need special mention are RFI and Snubber
Capacitors. They also make Intermediate Circuit Capacitors or DC-Link
capacitors, that can replace Electrolytics in SMPS or DC/AC Drives.
These capacitors are especially designed to attenuate voltage spikes
on GTO (Gate-Turn-Off) Thyristors and IGBT (Insulated Gate Bipolar
Transistor). They are manufactured in dry-type technology with a
dielectric of metalized polypropylene film and encapsulated in a
cylindrical plastic case sealed with self-extinguishing polyurethane
These caps have Very low self-inductance and High pulse reliability
(snubber). High rms current carrying capability (HF filter). Value
Ratings upto 100uF and 1KV available.
GTO Capacitors - WIMA
The Double Layer Capacitors developed by WIMA are storage capacitors
with highest capacitance values in the Farad range. They are among
others suited to serve as batteries, can deliver considerably higher
currents for a short time, however, and are maintenance free.
SuperCapacitors - WIMA
Despite the limitations of its maximum operating voltage of 2.5 V,
several cells can be built up to enormous capacitance of the desired
voltage by means of series or parallel connection (cascade). When
cascading SuperCaps, the voltage of single cells must not exceed 2.5 V
(decomposition of the electrolyte!)
Hy-Cap single cell model is divided into two categories: EDLC(Electric
Double Layer Capacitor), featuringa higher power, and Hybrid
Capacitor,featuring a higher energy density.
Hy-Cap is an energy storage device that stores instantly a large volume
of electric energy and supplies instantly or continuously higher
current, by the mechanism of absorbing and de-absorbing electric charge.
VINATech is the only producer in the world of catalyst support and
catalysts for fuel cells and MEA (Membrane Electrode Assembly).All of
these products are based on the company's patented CNF materials
"Hermetically sealed Evans Hybrid Capacitor and Capattery devices have
numerous patented features that provide demonstrated advantages over
standard capacitor technologies."
Evans Capacitor - High Energy Density Caps - https://www.evanscap.com/
"Evans maintains the highest levels of quality, and is fully compliant
with ISO 9001 and AS9001 standards." The unique chemistry and
construction provide 5 to 10 times the volumetric energy density of
aluminum electrolytic capacitors.
Technical Papers of Evans Capacitor
The Littlest Big Capacitor - An Evans Hybrid - Presented at the Fifth
International Seminar on Double Layer Capacitors and Similar Energy
Storage Devices, December 4-6, 1995
Capattery - SuperCapacitor - Designed for longer duration power hold-up and memory back-up applications. Full operating temperature range of -55C to 85C
High energy density, up to 3 joules per cc, High reliability, 25 yrs., >1,000,000 cycles
Hybrid capacitors provide very high power and energy from devices much
smaller and lighter than electrically equivalent tantalum wet, tantalum
chip, or aluminum electrolytic capacitors.
Typical applications replace standard military capacitors, or augment
batteries and power supplies where size, weight, reliability and quality
are important factors of component selection.

PoScope Mega1 is lowest power consumption USB oscilloscope, function generator and logic analyzer in one on the market. It draws only 60mA thus the best choice for measurement environments which demands power autonomy and longevity.
Integrated high quality analog to digital converters are able to sample up to 2,5MS/s and with maximum data resolution of 10mV at +/-20V input range.
Function generator is capable of generating different pattern test signals with frequency up to 12,5kHz and maximum amplitude of 1,8V. Logic analyzer captures up to 16 digital inputs and gathers data for further analysis. Included free software PoScope4 extends it’s usability for many different applications.
The PoScope4 software is multithreaded Windows application which enables usage of single or multiple PoScopeMega1 devices at same time. It’s core is based around plugin technology thus users can connect to it any measurement device by PoLabs. Parallel processing unit provides fast and smooth data acquisition and graphics drawing.
