A 64 x 128 real-time infrared (RTIR) complementary metaloxide semiconductor (CMOS)/ silicon-on-insulator (SOI) scene generation integrated circuit (IC) is described. The RTIR IC offers real-time dynamic thermal scene generation. This system is a mixed-mode design, with analog scene information written and stored into a thermal pixel array. The design uses micro-electromechanical sensors (MEMS) ...

We present a compact fluorescence imaging system developed for real-time sentinel lymph node mapping. The device uses two near-infrared wavelengths to record fluorescence and anatomical images with a single charge-coupled device camera. Experiments on lymph node and tissue phantoms confirmed that the amount of dye in superficial lymph nodes can be better estimated due to the absorption correcti...

The article presents the detection of gases using an infrared imaging Fourier-transform spectrometer (IFTS). The Telops company has developed the IFTS instrument HyperCam, which is offered as a shortor long-wave infrared device. The principle of HyperCam operation and methodology of gas detection has been shown in the paper, as well as theoretical evaluation of gas detection possibility. Calcul...

Existing large scale display systems generally adopt an indirect approach to user interaction. This is due to the use of standard desktop-oriented devices, such as a mouse on a desk, to control the large wall-sized display. By using an infrared laser pointer and an infrared tracking device, a more direct interaction with the large display can be achieved, thereby reducing the cognitive load of ...

Optoelectronic devices utilizing graphene have demonstrated unique capabilities and performances beyond state-of-the-art technologies. However, requirements in terms of device quality and uniformity are demanding. A major roadblock towards high-performance devices are nanoscale variations of the graphene device properties, impacting their macroscopic behaviour. Here we present and apply non-inv...

The THz spectrum lies between microwaves and the mid-infrared, a region that remains largely unexplored mainly due to the bottleneck issue of lacking compact, solid state, emitters and detectors. Here, we report on a novel asymmetric-nanochannel device, known as the self-switching device, which can operate at frequencies up to 2.5 THz for temperature up to 150 K. This is, to our knowledge, not ...

TableMouse is a cursor manipulation device designed specifically for multiple users interacting on large tabletop surface. TableMouse tracks position, height, orientation, button state, and unique identification. It is designed using infrared light emitting diodes and computer vision to perform device tracking and identification. This paper explores the functional design of such a device. Insig...

We present a low-cost, portable, wireless diffuse optical imaging device. The handheld device is fast, portable, and can be applied to a wide range of both static and dynamic imaging applications including breast cancer, functional brain imaging, and peripheral artery disease. The continuous-wave probe has four near-infrared wavelengths and uses digital detection techniques to perform measureme...

In this article we introduce an architecture of a mobile device that enables safe and authenticated data-transmission in a spontaneously configured network environment. The usage of this device is illustrated by a number of examples. The hardware and software components are presented. Particular, we compare Bluetooth and Infrared (IrDA) wireless networking technology, explain the usage of biome...

Most of existing biomedical signal measurement devices measure and evaluate biomedical signals only in a single device. Also, even if the device shows multi-functional characteristics, those biomedical signals can be measured by the selection of users. In this paper, a wristband-style biomedical signal measurement device for u-healthcare systems is implemented to solve the problem mentioned abo...
