Patent MX-PA04002568-A (MX)
Title: Digital transmission system with enhanced data multiplexing in vsb transmission system.
Inventor: WON KYUNG KANG
IPC: H04N19/89
Filed: 2004-03-18
Abstract: A digital VSB transmission system and enhanced data multiplexing method a re disclosed. When 1/2 enhanced data coded at a rate of 1/2 and 1/4 enhanced da ta at a rate of 1/4 are transmitted, timing jitter in MPEG of VSB receiver can be reduced and th e size of input buffer in MPEG decoder of the VSB receiver can be reduced by multiplexing th e 1/2 enhanced data packet and the 1/4 data packet at predetermined intervals. Multiplexing the 1/2 enhanced data packet and the 1/4 data packet by grouping increases the reception performance of the 1/4 enhanced data. Multiplexing the 1/2 enhanced data packet and the 1/4 data packet alternatively reduces the MPEG timing fitter in the VSB receiver and increases the reception performance of the 1/4 enhanced data.

Title: Method for producing a magnetic multipole encoder.
Inventor: ERDAL KAYA
IPC: H01F13/00
Filed: 2004-12-15
Abstract: A method for producing a magnetic multipole encoder with a carrier and at least one track made from a magnetizable material, in which the track made from magnetizable material is provided with strip-shaped magnetization of alternating polarity via the effect of an externally applied magnetic field. In a first step, the magnetic track is premagnetized with a uniform polarity and, in a second step, the polarity of the premagnetized track is reversed in strip-shaped regions. The method of the invention permits not only the use of simplified magnetization tools, but it can also be carried out faster and affords pole separations of the highest accuracy without additional optimization and adaptation steps.

Title: Techniques for correcting for phase and amplitude offsets in a mimo radio device.
Inventor: SUGAR GARY L
IPC: H01Q3/26
Filed: 2003-09-09
Abstract: Techniques are provided to correct for phase and amplitude mismatches in a radio device in order to maintain channel symmetry when communicating with another device using a multiple-input multiple output radio communication. Correction for the amplitude and phase mismatches among the plurality of transmitters and plurality of receivers of a device may be made at baseband using digital logic in the receiver path, the transmitter path or both paths of that device. Amplitude and phase offsets are determined among the plurality of radio transmitter and radio receiver paths by measuring phase and amplitude responses when supplying a signal to a transmitter in a first antenna path of the device and coupling the radio signal from a first antenna to a second antenna path of that device where the signal is down-converted by a receiver associated with the second antenna path.

Patent MX-PA05013916-A (MX)
Title: Pallet assembly.
Inventor: SMYERS JUSTIN M
IPC: B65D19/00
Filed: 2005-12-19
Abstract: A pallet assembly includes an upper deck and a lower deck spaced by a plurality of columns. In one embodiment, the columns are snap-fit into the upper deck and the lower deck. The weight of the pallet is reduced without significant reduction in strength by providing only a single cross beam in each of the upper and lower reinforcement members and orienting them perpendicular to one another. The reinforcement members are minimized for weight reduction and for improved performance in heat tests. The peripheral rail of the upper reinforcement member is reduced such that it rests on only an inwardly open recess on an inner corner of each of the corner columns. This reduces the size and weight of the upper reinforcement member, while still providing support to the upper deck. Additionally, the peripheral rails of both the upper and lower decks are reduced in length such that either ledge does not directly support them while the pallet is stored on a rack. As a result, in the case of sufficient heat source on the pallets, the pallets will eventually collapse without interference from the reinforcement members and at least partially smother the heat source.
Patent MX-PA06000833-A (MX)
Title: System and method for network transmission of graphical data through a distributed application.
Inventor: CALLEGARI ANDRES C
IPC: G06T15/00
Filed: 2004-07-21
Abstract: Systems and methods for network transmission of three-dimensional graphical data are disclosed. A single graphical application instance can virtually and efficiently exist on multiple local or remote display systems (102) by directly sharing its raw rendered framebuffer memory information (500) among all local or remote graphics accelerators (114), thus avoiding the need to re-render any application information again on each node. An internal graphics card (110) is used to scale the rendered data prior to transmission. This graphics scaling eliminates the need for data compression or image compression and achieves an adaptive, hardware-accelerated reduction in network bandwidth. Furthermore, since all memory and remote processing support tasks are performed within the graphics card, the CPU, system bus, and memory bandwidth remain available to the system and other applications.
