Polarized light imaging has been used to detect the borders of skin cancer and facilitate assessment of cancer boundaries. A design for an inexpensive handheld polarized camera is presented and clinical images acquired with this prototype are shown. The camera is built with two universal serial bus (USB) color video cameras, a polarizing beamsplitter cube, and a 4x objective lens. Illumination ...

The uses and capabilities of rogue USB hardware implants for use in cyber espionage activities is still very much an unknown quantity in the industry. Security professionals would benefit from tools capable of exploring the threat landscape while increasing awareness and countermeasures in this area. BadUSB 2.0 or BadUSB2 is such an investigative tool capable of compromising USB fixed-line comm...

Universal Serial Bus (USB) is a popular standard for PC peripheral devices because of its versatile peripheral interconnection specifications. USB not only provides simplified hardware connectors but also supports for various bus traffics, such as isochronous and bulk transfer activities. Although the USB specifications provide a way for users to specify the upper bound on the number of bytes f...

The strategy this work follows as to achieve its goal, is to put a very first stone in the way of making a USB peripheral. This is done by developing a USB I/O main-board that features some properties usually known of development board; however, this main-board is best identified as an I/O board as it remains in the final product (i.e. it is employed by the final USB peripheral), this identific...

This paper describes the design and development of low cost USB Data Acquisition System (DAS) for the measurement of physical parameters. Physical parameters such as temperature, humidity, light intensity etc., which are generally slowly varying signals are sensed by respective sensors or integrated sensors and converted into voltages. The DAS is designed using PIC18F4550 microcontroller, commu...

In this paper, we propose link-adaptive cooperative communication in wireless USB networks. To select the optimal relay node, we propose the RNS (Relay Node Selection) algorithm considering channel condition. Also, the proposed protocol can be directly applied with small overhead to the current wireless USB standard system. Furthermore, each device independently performs RNS algorithm by using ...
