Hitech Company obtained two new utility model patents authorized by the State Intellectual Property Office of the People’s Republic of China on June 12, 2009 and July 3, 2009 respectively, which are “A Kind of Circuit Amplified by Stages and Multifunctional Data Acquisition Card” and “External Slot 0 Controller”.
A Kind of Circuit Amplified by Stages and Multifunctional Data Acquisition Card is a multifunctional data acquisition card based on PXI or PCI bus, possessing the functions of analog acquisition, analog output, digital input and output, timing counter as well as programmable function interface function. It has 16-digit resolution, analog acquisition of multi-channel 1M scanning, and 4-channel 16-digit parallel analog output, etc. In addition to that, the card’s large onboard buffer can improve enormously the input and output buffer capacity and also meet the requirement of reducing the response speed of PC, thereby being applicable to multi-channel measurement with high speed and accuracy. This product is mainly composed of analog signal conditioning part, ADC (analog-digital conversion) part, DAC (digital-analog conversion) part, digital input and output (IO) part, analog triggering part, FPGA part, storage part, PCI part and power supply part. It is of remarkable value in engineering application.
External Slot 0 Controller includes the HTPCI4910 card based on PCI bus interface mounted on desktop computer or industrial personal computer, HTPXI491O card based on PXI bus mounted in PXI system, and the connecting cable between both cards. After the controller goes through the bus protocol conversion of PCI-to-StarFabric twice and builds up a PCI-to-PXI bridge between ordinary PC and PXI system, operations like data transmission, bus control as well as dependent interrupt and arbitration are all based on PCI protocol. This patent realizes a test system comprised of PXI chassis, which is controlled either by desktop computer or industrial personal computer, and therefore, it avails users of the convenience to carry out test on the product in test room or other working environments, and to save, analyze, and process the test data through the computer with powerful computational capability; meanwhile, the patent is also beneficial to the work on upgrading or expansion of users.
In the past few years, the company leaders attached great importance to the work on intellectual property protection and then worked out relevant reward policies gradually. These were then reciprocated by continuous reports of victory in patent application, and also promoted the technological innovation of the company in the field of test and measurement & control. The acquisition of these two patents was believed to be another fruitful accomplishment made by the company in technological innovation with respect to the field of test and measurement & control. It not only shows that the company’s ability in transferring scientific achievements keeps growing, but also is helpful to enhance greatly the market competitiveness of independent products of the company and the company’s popularity in the field.
