Electronic Product DesignDiarcy Technologies has expertise in all electronic disciplines — from RF, Wireless, and Cellular technologies to highly–complex Digital Designs using the latest products available on the market to Power Supplies, Audio Circuits, Opto–electronics, and so on. Diarcy Technologies designs all types of electronic products, sub–systems, and circuits. We continue to provide our customers with our wide–range of electronic design expertise. Whether you may need a specific electronic function or circuit as part of a larger system; or you are an Inventor that is looking to prove your concept and need a prototype made — whatever is your need, we can help. Our focus is on helping our customers lower their risk by providing expertise in product design and development, resulting in an accelerated time–to–market for their product announcement and delivery. Let us know how we can help you.
Cellular Product DesignWe have designed several instrumentation products for the Cellular Market. These products include Cellular (GSM, PCS, UMTS, LTE) Receivers that provide I/Q–quadrature outputs to allow further demodulation or decoding. The baseband data can be processed on–board with highly–complex digital algorithms embedded in FPGA–logic or the data can be passed to a Personal Computer (PC) for further analysis (e.g. in MATLAB).
In addition to our Receiver Design, we have also designed small–signal Cellular Transmitters. These transmitters can be used as localized testing sources and can cover all Cellular bands (GSM, PCS, UMTS, LTE). (Click here for more information...)
Wireless and RF Product DesignOur design expertise extends from DC through 18 GHz. We have even done some 35 GHz and 94 GHz work. Our current focus, however, is targeted at the wireless market. Specifically, we have designed products for the ISM (Industrial, Scientific, and Medical) frequency bands. These products include wireless asset tracking devices, personnel monitoring systems, and an automated utility meter data collection system.
Some specific product examples include miniaturized transmitters that fit on the end of golf clubs to protect the clubs from being lost; child or Alzheimer's patients monitoring systems that alert you if the person is beyond a certain distance from a monitoring receiver; and data collecting systems to retrieve readings from water, gas, and electrical meters. Typical ranges are up to 300 feet.
All of these products are similar in nature and are only limited by what the FCC (Federal Communications Commission) allows us to do. Our flexible designs enable us to quickly turn your product ideas into new designs. Some examples include anti–loss devices that fit into laptop computers, briefcases, purses or other valuable assets.
For most applications, we use our own discrete transmitters that are nominally half the cost of the common wireless modules. This results in an enormous savings during production. For Part 15 applications in the United States, commonly available frequencies are 315 MHz, 418 MHz, and 916.5 MHz.
Antenna Design and AnalysisComplementing our Wireless and RF design specialty, we design our own antennas. This allows us to tailor an antenna specific to your needs. We use both wire and planar antenna technologies for our transmitters and receivers. The benefit of having this capability is the cost savings realized in production.
In addition, we have analytical models to analyze our antenna structures to maximize their performance. These specialized software codes allow us to setup and check for impedance match and radiation patterns.
We also can analyze your antenna designs. We use a highly accurate method of moments (MoM) analysis code for wire geometries and a geometrical optics analysis code for large planar geometries. We can produce impedance variations over frequency, voltage standing wave ratio (VSWR) over frequency, current distributions along the antenna's surface or length, radiation patterns over frequency, and radiation patters over aspect angle.
Microcontroller Embedded DesignTo keep production costs low, we use microcontroller technology in our designs whenever possible. Using microcontrollers allow us to replace many hardware level functions into a single chip. This results in additional cost savings during production. Further, it allows us to keep the design flexible so that if changes are needed later, we can change the firmware code without having the change the electronic parts or modify the board design.
We use the microcontrollers to generate the baseband modulation waveforms for our wireless products. This keeps our designs very flexible by being able to change the protocol to suit your needs.
We can also use the microcontrollers to interface into personal computers so that data stored in your wireless device can be transferred back and forth between your device and the computer.
Still another use is to use the microcontroller to interface into LCD modules to display text information, interface into numeric keypads to input user data, initiate a call sequence to an automatic telephone dialer, light or flash LEDs, sound buzzers, etc. These devices are very flexible and can result in huge cost savings to your production costs.
We exclusively use Microchip Technology microcontrollers. We have been working with these devices for over 20 years. Microchip has a wide range of models available to meet your needs.
Analytical Software DevelopmentIf you have specific software development needs, we can help. We have provided our clients with PC–based software analysis tools to help analyze data or even to provide data converters. As an example, one client needed to have AutoCAD DXF data converted to another format specific to their proprietary analysis code. We were able to extract all AutoCAD data and convert this into the format needed by our client. In another case, a client needed binary data retrieved from their Hewlett–Packard gas chromanograph converted to ASCII data for the PC. These are just two examples of how our diverse high technology background was put to use to solve these unique problems.
