Acumen Instruments Corporation[tm] is a leader in embedded storage and connectivity solutions. Acumen's DataBridge[tm] technology revolutionizes data collection, storage, and communication by integrating these functions in a single chip. Our customers are realizing clear productivity gains by leveraging DataBridge technology to eliminate expensive, power-hungry PC-based data systems.
We partner with manufacturers to develop customized applications based on DataBridge technology. Acumen provides a range of solutions from single chips to custom circuit boards to enable instruments to be networked and linked with convenient, affordable, off-the-shelf consumer storage devices. With DataBridge technology, sensors and instruments become stand-alone information devices.
Since Acumen's incorporation in 1997, DataBridge technology has been used in applications to record process monitoring data, log industrial sensor output, and monitor air quality. The technology is also being used to store high-volume data generated by GPS reference stations and data from medical monitoring equipment. Our products have been proven in environments ranging from factories and laboratories to forest canopies and Antarctic mountaintops.
The Acumen Instruments Corporation's proprietary DataBridge technology and its in-house engineering expertise are successfully helping worldwide manufacturers, across many industries, to enhance existing products and to develop new products with reduced costs, reduced power consumption, and reduced system complexity, while increasing system stability and dependability.

Widely recognized as an innovator and technology expert in the integration of hardware/software systems on semiconductors. It combines the strengths of Alcatel's advanced communications systems design teams with the mixed digital/analog ASIC expertise of the former Alcatel Mietec division. Pooling the systems expertise of the 10,000 engineers within Alcatel, the company has constructed a substantial library of re-usable intellectual property (IP) components. Levering this expertise, Alcatel Microelectronics is offering communications standards products to key players in the telecom, automotive and peripherals markets. The company operates globally with a network of sales and design centers located in the key markets of Asia Pacific, the USA and Europe. Those locations enable close customer contact, maintaining the corporate philosophy of client focus and customer driven design.

(The mother company Acer makes computers. It also makes components like motherboards, PC cases and CD-ROM drives under the brand name Aopen.)
In 1987, while the personal computer industry was blossoming worldwide, a group of computer technologists envisioned the critical role ASIC development would play in this emerging market. They formed a team dedicated to bringing their individual expertise in IC development, design, application and service to the PC industry. This was the beginning of Acer Laboratories Inc.
Through well over a decade as a major player in the PC market, ALi has pursued its goal of bringing value to PC system and motherboard manufacturers. ALi has successfully developed a talented and resourceful infrastructure to support complete product lines, highly efficient and flexible production, real-time customer service, and continuous technology integration. ALi has created innovative leading products including the first industry standard Super I/O controller, the first RISC based PC system chip set, the first 100MHz Socket 7 chipset and the first complete DVD solution. Multiple best-product awards have been awarded to the company, along with significant patents and software copyright registrations. In fact, throughout its years of dedication to the PC industry, ALi has developed one of the industry's richest PC-related Intellectual Property (IP) collections covering system, peripheral and multimedia devices.
