Harwin - Interconnect Devices - Connectors

Harwin designs and manufactures world class electrical and electronic interconnect solutions. From standard and ultra-fine connectors and PCB components.

Harwin - Interconnect Devices - Connectors

The new Harwin backshells can be used in conjunction with both the company’s J-Tek and its Mix-Tek Datamate connector product lines - with signal, power and coax cabling all being accommodated. The combined Datamate/backshell assemblies are significantly lower in overall cost than equivalent Micro-D/backshell arrangements.

PC User Interface and Wireless Power

Wireless Charging is a Reality today, it was first conceived by me in the 90s. The first page published related to that in my netscape site.

This was conceived to get rid of cables for data and power on my desktop. I felt if we use Optics for Data and Wireless Ferrite Contact Plates to transfer power, there would be no wires at all on the desk. I even experimented with RS232 Serial Port and Ferrite Slices below thin Acrylic Plastic Sheet, it worked.

I did not patent any of my concepts, but it is offered to all humanity as an Open Design, like all my other work.

Here is a planar transformer which has PCB tracks for winding. This show that there is more scope of innovation in such ferrite transformers for short range wireless power.

PC User Interface and Wireless Power

Objects kept on a electromagnetic table must be able to draw energy from that. A Notebook or tablet can be just placed on this table to get charged.

The optic ball-less mouse is a great step in mice-tech user-interface. This mouse consumes more power, for a wireless mouse a capacitive sensor matrix based sensing may be better.

Touch Screen on PC is not common place. A combination of Touch screen and Mouse is excellent for all age-groups. Large monitors can have at least two inches of touch screen area at bottom.

Laptops, LCD Monitors make UPS (Uninterrupted Power Supply) last longer and it reduces electricity costs.

 Wireless Power for Wireless Peripherals

Wireless Mouse with capacitive sensors may consume less power, no batteries works on a Supercap, Connector-less ferrite dock for recharging

Wireless mouse rechargeable battery can recharge while moving on the Mouse Pad made of Ferrite/Ceramic 1′ Sq with Power Hot Spots every 3″

Flexible Ferrite, Silicone & Ferrite based Solid emulsion. Can be made as computer table mats to charge the supercaps of peripherals.

The Energy Efficient Wireless Peripherals can just be placed on this mat to draw the power without wires. Wireless power and Wireless Data.

Usability and Ergonomics Review
Aggregated Notes from 2008-12

Usability and Ergonomics of Electronic Consumer Equipment, product risks and safety are best studied with very old and very young people.

Personal Computers, Netbooks, Portable Communicating Devices, Remote Controls are where Usability Issues abound, and can be studied/remedied.

Optical Rotary Encoders, Magnetic/Eddy/Capacitive/Hall Effect based Non-Contact Joysticks, Makes Human An analog Interface with Digital Output.

For the people who type with two fingers; A Circular Keyboard is right. A Capacitive Touch Gesture Pad can replace the Mouse. Health & Ergo.
