Piezoelectric BendersPiezoelectric benders are often used to create actuators withlarge displacement capabilities. The bender works similarly to theaction of a bimetallic spring. Two separate bars or wafers ofpiezoelectric material are metallized and poled in the thicknessexpansion mode. They are then assembled in a +–+– stackand mechanically bonded. In some cases, a thin membrane is placedbetween the two wafers. The outer electrodes are connected togetherand a field is applied between the inner and outer electrodes.

Along with the acquisition, Broadcom will gain Vinod Dham, chairman, president and CEO of Silicon Spice. The former Intel Corp. manager, who headed up the Pentium processor program, will join Broadcom's management team.

Vin brings to Broadcom many years of industry experience in delivering advanced silicon-level systems,” Nicholas said.

According to Broadcom, Silicon Spice invented a new signal processing architecture, which when implemented within carrier access systems and gateways, can surpass the density, power dissipation, and remote-provision ability of any existing voice-over-packet network solution. The architectural techniques include reconfigurable adaptive instruction sets, hierarchical digital signal processor (DSP) multi-processing, and hybrid RISC/DSP implementation. Silicon Spice claims it has demonstrated the highest channel densities ever achieved in a single chip.

With Broadcom's critical mass, we can now extend the architecture to address other DSP-centric markets such as multiport DSL and 3G wireless base stations,” said Dham.

SAN JOSE — Atmel Corp. here today announced it has licensed Motorola Inc.'s 0.35-micron BiCMOS technology for radio-frequency ICs and plans to act as a second source of RF chips in wireless applications using that process.

This licensing agreement allows our customers to source Motorola's 0.35-micron advanced RF BiCMOS technology directly from Atmel,” said Behrooz Abdi, general manager of Motorola's RF/IF Division in Phoenix. We'll continue to pursue both foundry and second-source arrangements to ensure supplies to our customers in this accelerating market.”

The 0.35-micron process is the third generation of Motorola BiCMOS technology to be licensed by Atmel for RF and intermediate frequency (IF) functions in wireless systems. The licensing pact enables Atmel to accept designs from equipment manufacturers and produce fully mask-compatible parts using Motorola's technology. The financial terms of the licensing arrangement were not disclosed.

The two companies said the licensed technology has a 0.35-micron feature size and an NPN transition frequency (ft) of 28 GHz. The BiCMOS process supports the integration of digital functions with RF mixers, low-noise amplifiers, voltage-controlled oscillators, gain-controlled amplifiers, and frequency synthesizers, as well as baseband analog functions (signal strength detectors and filters).

The 0.35-micron technology is aimed at cellular phones, cordless phones, global position satellite (GPS) receivers, wireless local area networks (LANs), and transceivers for the unlicensed Industrial, Scientific, and Medical (ISM) bands up to 2,400-MHz.

Have you seen that little gem of a website – Animated Knots by Grog. I ran across this via the Yahoo How Things Work [HTW] group. It started when someone posted a message saying something like Here's an interesting variant on tying a shoelace knot that I didn't know about.” (In case you were wondering, the knot in question is called a Shoelace Bow).

So I bounced over to take a look and – you probably won’t be surprised to hear – was immediately sucked in. This is a really, REALLY useful site. It covers 120 different knots from the Albright Knot to the Woggle (this latter one is something I'm going to check out as soon as I've finished this blog because it sounds like a happy, friendly knot I'd like to get to know better). For each knot there's a text description of how to tie it along with details on its structure and uses. But the best part is the step-by-step animations, which make it incredibly easy to understand the process of tying the knot.

Of course the folks in the HTW group couldn’t let things stop there. One of the guys responded as follows:

My standard way to join two slippery ropes (nylon or other similar synthetic) I learned from my father. Tie a figure-8 knot in one rope; follow the figure-8 with the other rope in the opposite direction (i.e., starting at the first rope's end). Pull snug. The result is a nice bend that won't slip and still is fairly easy to loosen.

This prompted someone else to reply:
