An imaging and decoding system for an imaging-based bar code reader. The imaging and decoding system includes an imaging system and a decoding system. The imaging system includes an imaging pixel array and a memory which function to: image the target bar code by scanning the target bar code at an acute angle with respect to a vertical axis of the target bar code to generate a tilted imaged bar code stored in memory, the tilted imaged bar code comprising an array of gray scale values stored in the memory; generate a virtual scan line traversing a horizontal width of the tilted imaged bar code; establish a zone about the virtual scan line; and project gray values within the zone onto the virtual scan line thereby generating a sequence of gray scale values associated with the virtual scan line, the sequence of gray scale values representative of a pattern of elements of the target bar code. The decoding system decodes the target bar code utilizing the sequence of values associated with the virtual scan line.

A client computing architecture is provided that utilized minimal download and simulated page navigation features. A client computer may receive a payload comprising delta data in response to a navigation request for an electronic page. The client computer may further parse the delta data for the electronic page, update page contents for the electronic page based on the received delta data, determine whether one or more errors are associated with a page load process for the electronic page, manage a fragment identifier portion of a uniform resource locator (URL) to track a current location in a navigation of the electronic page, and intercept one or more navigation click events to ensure a minimal download strategy navigation.

Disclosed is a fishing line spool assembly including an open body frame, wherein a fishing line spool is mounted between two side plates of the body frame at an open end, has a central bore, and is rotatably sandwiched between the two side plates by a clamping adjustable device inserted through the central bore of the fishing line spool and bores of the two side plates. The body frame is provided with a connection device for connecting to a fishing rod. With the present invention, the clamping force applied on the fishing line spool by the two side plates can by adjusted by the clamping adjustable device. When the fishing line in the fishing line spool is drawn by a fishing reel, the clamping force on the fishing line spool by the body frame will function as a brake against the rotation of the fishing line spool.

To address counterfeit problems, for example, we propose a secure, flexible, and cost-effective authentication solution that can be integrated into conventional distribution logistic systems. The proposed solution for product authentication and distribution channel validation comprises three major components: 1) machine-readable Raman-active chemical taggant; 2) a taggant reader; and 3) a taggant eraser. The proposed solution is to control and validate the distribution channel by authenticating the origin of products. Authentication is accomplished by verification of distinct taggants associated with the articles, such as on its label, along with other product distribution information in optical, spatial-encoding indicia, such as a barcode. The taggant information is used to identify, validate, and distinguish the origin of the source of the articles, such as goods or products. The taggant material is thereafter rendered unreadable by modifying the taggants to make obtaining the information unfeasible, thereby controlling the taggants' lifecycle.

A method and system for facilitating the transmission and delivery of mobile messages during a mass mobile messaging event. Dedicated message centers and messaging gateways are provided to route mobile messages associated with mass messaging events to and from their intended destinations. Such a configuration avoids the creation of undue latencies in the delivery of mobile messages that are not associated with mobile messaging events while providing an efficient mechanism to facilitate mass mobile messaging.

A spectrometer that provides the ability to combine the advantages of high resolution, compactness, ruggedness, and low-power consumption of Fabry-Perot (FP) tunable filter spectrometer, with the multi-channel multiplexing advantage of FT and/or grating/detector array. The key concept is to design and operate a tunable FP filter in a multiple-order condition. This filter is then followed by a “low-resolution” fixed grating, which disperses the filtered n-order signal into a preferably matched N-element detector array for parallel detection. The spectral resolution in this system is determined by the FP filter, which can be designed to have very high resolution. The N-order parallel detection scheme reduces the total integration or scan time by a factor of N to achieve the same signal to noise ratio (SNR) at the same resolution as the single channel tunable filter method. This design is also very flexible, allowing spectrometer systems with appropriate order N to thereby optimize the system performance for spectral resolution and scan integration time. In addition to the significant reduction in scan integration time, there are two other advantages to this approach. The first, because the FP tunable filter is designed and operated under n-orders, the fabrication tolerances of the FP filter cavity and operating conditions are significantly loosened.

An integrated optical line card protection module uses free-space optical links to thereby increase the level of integration while decreasing footprint. The module comprises a bench, a user-side interface to an array of user fibers and a device-side interface to an array of device fibers. The device fibers connect the module to a primary device and a redundant device. A monitoring signal generator is provided on the bench that provides monitoring signals. A monitoring signal detector is also on the bench that detects the monitoring signals. Finally, a beam switching system is provided that selectively connects the user fibers to the device fibers of the primary device or the device fibers of the redundant device. The preferred configuration is in-line with the user-side interface on an opposed side of the module relative to the device side interface. This is accomplished with translating switching system.

A fiber array apparatus and formation method mitigates or eliminates height offset and/or angular offset of the respective fiber cores in the array. In one aspect, the fibers are mounted in the array such that the respective core-to-clad offset axes of the fibers, defined between the fiber core center and the cladding center of each fiber, are substantially parallel. In another aspect, the plurality of fibers are cut from the same fiber spool, ensuring consistency in cladding outer diameter. In this manner, precision in core-to-core pitch and consistency in core-to-core height are achieved in the fiber array.
