“…The other way of producing quasi‐Bessel beams is to manipulate the phase of the input light beam. Phase modulation, either through a phase mask or a spatial light modulator (SLM) , can lead to a variety of Bessel beams with different orders . But the phase modulation is only fit for a particular wavelength or a very narrow spectral bandwidth, which tends to fail in our broadband OCM imaging system.…”

Optical coherence microscopy (OCM) has unique advantages of non-invasive 3D imaging without the need of exogenous labels for studying biological samples. However, the imaging depth of this technique is limited by the tradeoff between the depth of focus (DOF) and high lateral resolution in Gaussian optics. To overcome this limitation, we have developed an extended-focus OCM (xf-OCM) imaging system using quasi-Bessel beam illumination to extend the DOF to ∼100 μm, about 3-fold greater than standard OCM. High lateral resolution of 1.6 μm ensured detailed identification of structures within live animal samples. The insensitivity to spherical aberrations strengthened the capability of our xf-OCM system in 3D biological imaging.

As new mobile devices such as cellular phones, PDAs, laptop computers, and touch screen computers become more and more popular, many people want to be able to access the internet without limitations. Rapid advances in various wireless access technologies such as wideband code division multiple access (WCDMA), mobile worldwide interoperability for microwave access (M-WiMAX), long term evolution (LTE), wireless local area networks (WLANs), and wireless sensor networks (WSNs) respond to consumers' demands for mobile and ubiquitous computing environments.As the number of network devices supporting the IPv4 protocol has been rapidly increasing, a shortage of IPv4 addresses to assign to new devices has arisen. To address the shortage in the IP address pool, the Internet Engineering Task Force (IETF) has proposed an IPv6 protocol with 64 bit addresses [1]. However, because mobility management is not supported in IPv6, Mobile IPv6 (MIPv6) [2] has also been standardized by the IETF. MIPv6 does not define a foreign agent (FA) and supports an optimized routing path through which a mobile node (MN) can communicate directly with a correspondent node (CN). Careful consideration has been required, however, to avoid a heavy and complicated MIPv6 protocol, which could cause several critical problems in wireless mobile devices, such as poor CPU performance, a large power consumption, and a shortened battery life. To overcome these problems in wireless environments, a network-based mobility management solution called Proxy MIPv6 (PMIPv6) [3] is standardized by the IETF Network-Based Localized Mobility Management (NETLMM) working group. In a PMIPv6 protocol, the mobility management ___________________________________________________________________________________________

This paper proposes an efficient hardware architecture for high efficiency video coding (HEVC), which is the next generation video compression standard. It adopts several new coding techniques to reduce the bit rate by about 50% compared with the previous one. Unlike the previous H.264/AVC 6-tap interpolation filter, in HEVC, a one-dimensional seven-tap and eight-tap filter is adopted for luma interpolation, but it also increases the complexity and gate area in hardware implementation. In this paper, we propose a parallel architecture to boost the interpolation performance, achieving a luma 4×4 block interpolation in 2-4 cycles. The proposed architecture contains shared operations reducing the gate count increased due to the parallel architecture. This makes the area efficiency better than the previous design, in the best case, with the performance improved by about 75.15%. It is synthesized with the MagnaChip 0.18 μm library and can reach the maximum frequency of 200 MHz.
