Cmos amplifier design jobs

I was recently awarded a patent for a modified beverage cooler that has waterproof speakers. I need a 3D model of the design so it can be rotationally molded. It needs to have 2 parts: an exterior shell that measures 20" x 12" x 11.5"; an interior shell that fits into the exterior shell that has 1" of empty space between the shells for insulation. A lid needs to be included in the design as well. Modifications: The front of the cooler must have a hollow panel that extends from the front in order to accommodate 2 speakers that have a mounting dept of 2", as well as a mini amplifier module. There need to be 2 circle holes in the panel with a 4.5" diameter for the speakers to be mounted in. The bottom of the cooler needs a cavity that ...

The basic circuit is a 12 volt solid electrolyte Werker WKA12-5F battery lighting an LED of 3 to 9 watts. The circuit you designed cuts off the LED as required.

However, the battery voltage recovers by about 0.2 volts when the load is dropped. This causes the operational amplifier to reset the relay causing the relay to chatter and the LED to blink rapidly. Once the circuit has been interrupted it needs to remain off. Only the circuit diagram and components needed required. I will handle testing and PC board...

... units today others have been attempted to use are just not small enough, nor can they be implemented into a helmet for "full contact." We are looking for an engineer with past experience in building wireless devices, preferably WiFi, and with the expertise, knowledge and experience in building the actual PCB board (or finding someone that is capable). The unit is quite simple: CMOS camera (cell phone camera), processing chip, WiFi chip (5GHz), battery management chip, 1-2 antennas and the battery; obviously, size is an issue. Here is a good size comparison of what we are looking for. We have a mock prototype built to-date. Furthermore, our company is patent

...amplifiers in the network will shut off at high input levels, we need the microphone input to be filtered. First it should be amplified such that a user who speaks softly or is too far away from the mic will still be heard. Second the signal should be compressed for optimum speech intelligibility. Third it should be limited not to overload the amplifier. As we are working from Power over Ethernet, we have to squeeze the most out of the power available, so the amplifier operates near its maximum. Hence, *** the limiter should not only cut off peaks but limit the effective power *** in the stream to a maximum. This requires integration of the signal over time. It should also make use of the Windows's functionality to set the mic level if the input level is too high (li...

Calling all audio enthusiasts with a knowledge of circuit design and implementation. Hi, we are building a unique home audio system. We were thinking use the speakers from a decent quality 6 x 9 inch car audio pair and integrate into a custom designed amplifier. You can see sketches and circuit suggestions attached. We require design of circuit and advice on the speaker mould which we are custom designing. The sketches will shed more light and we require a full proto-type version to be created. We will assist in sourcing the parts and having the mould created. i have some more detailed circuit diagrams that may help, but personal knowledge of the best circuit layout and chips is essential. Thank you for looking into this in advance and look forward to h...

Project is to design a small board which will take analog & digital (YCbCr) 1080p video data from a standard HD camera ( For ex. Sony FCBEH6500), and compress it with H.264 down to at most 10 Mbps BW. Output should be parallel or series compressed LVDS or CMOS video data. Low cost solutions will be preferred. * Board will also have 2 SD video (NTSC/PAL/SECAM) inputs and SD card record option. * Just Schematic design with related software will be desired from the employee.

The MATLAB M-files and GUI will have playing, stitching, editing features to simulate normal and defective ECG signals such as arrhythmia, apnea, and congestive heart failure. The signals can then be converted into actual electrical signal by using the DAC of the built-in-sound card (speaker port) and an external analog amplifier for post-amplification. This human ECG simulator can be used to test electronic circuits for ECG analysis.

I am working on a project which is just complete. i have an analog signal in the range of 2v-3.3v,. I have a ADC LM231 which I need to use with the FPGA (3E XC3S100E) to detect a signal coming from a microphone. In this project we are supposed to shoot a sound producing source(1000HZ & 2500Hz) with a moving tank, we need to use a microphone to pick up signal, use amplifier and band pass and send it to ADC which will give digital output, the digital output is fed to FPGA and the FPGA will decide if the source is present, then the FPGA will stop the tank from moving right in front of the source and will shoot it. Basically i have everything done and I have the ADC(Voltage to frequency converter) with me. Just need that analog to digital conversion and using the data in Verilog . ...

Similar to how Soundbender works on the iPad, looking to create one for the all popular Samsung Galaxy S3 that functions the same but with an additional feature of having that sound amplifier also acting as a phone stand that tilts your phone to an optimum angle for watching a movie on your phone. Draft visuals of the idea attached. Looking for a someone who's able to design a ready-to-prototype (can be 3D printed straightaway) visual of the device. Criteria: 1. It has to actually bend the sound forward from the back of the phone. 2. Looks real sexy. 3. Not bulky, something that you wouldn't mind carrying around.

...blocking filter in front of the ccd or cmos sensor, sensitive to the near infrared light in the range 700-1000nm. But colours image sensors are optimized for day-light use, their sensitivity in the near infrared range is low, and they are not low-ligh enhanced. Monocrome sensors are much more sensitive in the near infrared range, and some have been optimized for these freq. range. Take for example the photonfocus A1312I, which has a quantum efficiency of 40% at 900nm. The idea behind this job is creating a prototype of a night vision HD DVR. Phase 1: Image sensor choice The image sensor must be optimized for infrared night vision in the range 900-100nm. Photonfocus A1312I is an option, others will be evaluated. You can evalutate ccd or cmos. HD sensors a...
