Abstract: A process for the production of polytrimethylene terephthalate (PTT), wherein the process comprises: (i) one or more esterification steps, wherein terephthalic acid (TPA) or an alkyl diester of terephthalic acid is reacted with 1,3-propanediol (PDO); and (ii) one or more subsequent polycondensation steps, wherein the process further comprises the addition of a protic acid, other than terephthalic or isophthalic acid, before and/or during the one or more esterification steps, wherein the protic acid has a dissociation constant of at most 4 (pKa measured in water at 25° C.), and wherein the total amount of protic acid added before and/or during the one or more esterification steps is in the range of from 0.001 to 10 millimole of acid per kilogram of polytrimethylene terephthalate produced.

Abstract: A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

Abstract: A jack handle includes a handle arm having first and second ends, a jack driver having a coupling shaft, and a spring clip detachably securing the jack driver to the handle arm. The first end of the handle arm forms a socket receiving the coupling shaft. The spring clip has a protrusion resiliently deflectable between a locking position interlocking with the coupling shaft to secure the jack driver to the handle arm and a releasing position free of the coupling shaft such that the jack driver is released from the handle arm. Preferably, the spring clip encircles the periphery of the handle arm at the socket, the handle arm has an opening at the socket, and the protrusion of the clip extends through the opening and into the groove to interlock the jack driver with the handle arm.

Abstract: A vehicle entertainment and accessory control system (10) is disclosed. The control system (10) provides a plurality of touchscreens (12,14,16) that present user interfaces (38,62) concurrently with video windows (40,64). The user interfaces (38,62) enable users to control various entertainment components, such as a video display (22) and a speaker (24), as well as other vehicle accessories, such as an intercom (28). The entertainment components are controlled via a universal infrared controller (20). A master touchscreen (12) enables a user to control access to the system (10) via a plurality of passenger touchscreens (14,16) by disabling or limiting the use of the passenger touchscreens (14,16).

Abstract: Acoustic telemetry systems and methods with surface noise cancellation. One illustrative embodiment may include an acoustic telemetry system comprising a transmitter configured to generate an acoustic information signal that propagates along a drillstring, and a receiver configured to detect an acoustic receive signal from the drillstring and a noise signal from a surface environment. The receiver operates on the acoustic receive signal and the noise signal to produce a modified signal indicative of the acoustic information signal and having a reduced noise content relative to the acoustic receive signal.

Abstract: Methods and systems employing combined source-channel coding for multi-carrier modulation (MCM). In some embodiments, a described method comprises: estimating channel gain to noise ratio (CGNR) as a function of frequency bin; determining MCM parameters that minimize distortion of one or more telemetry signals; generating a communications signal using the MCM parameters, and transmitting the communications signal via a communications channel. The MCM parameters may be determined by minimizing a telemetry signal distortion measure subject to CGNR and a transmit power constraint. The MCM parameters may further account for differing fidelity requirements when multiple telemetry signals are being transmitted.

Abstract: Acoustic telemetry devices and methods that provide directional detection. In one embodiment, a disclosed acoustic telemetry device comprises at least two acoustic sensors and an electronics module. A first of the acoustic sensors detects a communication signal that propagates along a tubing string in a first direction. A second of the acoustic sensors is configured to detect the communication signal before the first acoustic sensor. The electronics module combines the detection signals from the acoustic sensors to obtain a combined signal that substantially excludes signals propagating in a direction opposite to the communication signal. Such signal suppression may significantly enhance the communication signal's signal-to-noise ratio, thereby increasing channel capacity. The acoustic telemetry device may be configured to support logging while drilling and/or full-duplex communication.
