This paper begins by highlighting key features of the Bluetooth baseband standard. Software simulated results for the transmission of symmetric asynchronous data link (ACL) packets are used to discuss bit rate capabilities of various timebounded and non-time bounded Bluetooth enabled consumer electronic devices. The investigation considers Bluetooth data medium (DM) and data high (DH) packet ty...

We report the detection of periodic (p = 1.96 hours) bursts of extremely bright, 100% circularly polarized, coherent radio emission from the M9 dwarf TVLM 513-46546. Simultaneous photometric monitoring observations have established this periodicity to be the rotation period of the dwarf. These bursts, which were not present in previous observations of this target, confirm that ultracool dwarfs ...

General agreement has been reached recently, that the coherent optimum receivers known from the theory of conventional communication systems are not feasible to implement low-cost and robust UltraWideBand (UWB) Impulse Radio (IR) receivers, especially if they have to offer an extremely low power consumption. Instead, Energy Detector (ED)-based noncoherent receivers have to be used [1]. Unfortun...

introduction: different dosimetric modalities (e.g., ionization chambers, semiconductors, tlds, radiographic films) often have some problems determining isodose curves and percentage depth doses in high dose gradient regions. research has been ongoing to develop portable high resolution dosimetry devices with accurate absolute dosimetry capabilities and easy data analysis. the ‘presage’ dosimet...

We place direct upper limits on the amplitude of gravitational waves from 28 isolated radio pulsars by a coherent multidetector analysis of the data collected during the second science run of the LIGO interferometric detectors. These are the first direct upper limits for 26 of the 28 pulsars. We use coordinated radio observations for the first time to build radio-guided phase templates for the ...
