摘要:
A power supply history monitor. The monitor receives a short duration anomalous signal, e.g., from a power supply, and produces a digitized signal representing the anomalous signal as an output. The monitor receives a signal from a signal input, and includes an analog delay element in series with the signal input, a sample and hold element receiving a signal from the analog delay element, an analog signal processor receiving an output of the sample and hold element, and an analog to digital converter receiving an analog output of the analog signal processor. The output of the power supply history monitor is a digital output.

The lower power on-chip power supply noise sensor detects high frequency overshoots and undershoots of the power supply voltage. The sensor has two resistor chains that span the full power rail, with a reactive element to form a low pass filter as part of one of the resistor chains. By this expedient the high frequency transient behavior differs between the two chains, while the low frequency behavior is equivalent. This allows a voltage comparison to be made with comparators. The comparator output can be latched or transmitted as a sampling signal.

A medical device for temporarily treating an individual having a flail chest injury prior to and during transport of the individual for further medical treatment. The medical device includes a flexible member engageable with a flail segment of an individual that provides skin traction to the flail segment of the individual for stabilizing paradoxical motion of such flail segment during respiration. There is an adhesive layer disposed on the flexible member for temporarily adhering it to the flail segment of the individual.

A document construction and management system is described. In one embodiment, documents are assembled by combining one or more modules. In one embodiment, the modules are combined according to one or more construction rules. The modules can be provided to a number of subscribers, each subscriber having one or more users. Access to each of the modules can be controlled on a subscriber basis and/or on a user basis based on different users or user classes. When new modules or new versions of an existing module are added to the database of available modules, access to the new module or version can be restricted until the new modules or versions have been reviewed and accepted. During the review period, the previous version of the module is made available to users for construction of documents. In one embodiment, one or more access rules are used to control which modules are available to which users. In one embodiment, search rules are provided to facilitate searching for a desired module.

A state detection circuit for a fusible element includes a differential sensing circuit that compares voltage at a detection point in a path containing the fusible element with that at a reference point in a path establishing a non-zero reference voltage. The paths are similarly configured except one contains the fusible element while the other contains a device establishing the reference voltage. The two paths in any given sensing circuit are located in close proximity to each other so that even though element parameters in the paths of different sensing circuits may vary significantly, those values track each other in the given sensing circuit. As a result, the normal non-zero value of the voltage at the reference point maintains a relationship to that at the detection point that enables the differential sensing circuit to detect between a fused and an unfused element irrespective of variation in circuit element parameters. In order to prevent detection circuits and other circuits on the chip being damaged, during blowing of the fusible elements, voltage level of the sensing circuits are chosen to isolate the detection circuits from the other circuits on the semiconductor chip and the excitation levels applied to the detection circuits are raised to maintain differential voltages in the detection circuits at sufficiently low levels to prevent damage.

Devices and methods are provided for treatment of tissue in a body lumen with an electrode deployment device. Embodiments typically include a device with a plurality of electrodes having a pre-selected electrode density arranged on the surface of a support. The support may comprise a non-distensible electrode backing that is spirally furled about an axis and coupled to an expansion member such as an inflatable elastic balloon. In some embodiments, the balloon is inflated to selectively expose a portion of the electrode surface while maintaining the electrode density.

The invention relates to an optical reading system comprising an optical reader and a host processor. In one aspect of the invention, the host processor may be configured to transmit a component control instruction in response to a user input command input by a user of the host processor to remotely control the reader. The optical reader subsequently receives the transmitted component control instruction and executes the component control instruction substantially on receipt thereof. In one embodiment, execution of the component control instruction by the optical reader has the same effect as the reader trigger being manually pulled by a reader operator.

A sorting system may include a sorting apparatus coupled to a programmable control system which is configured to actuate the sorting apparatus so that it assembles similar products for packaging in an arbitrary, user imposed order or selection bias. In preferred implementations, a user may activate a biasing protocol pursuant to which items bearing certain images appear with a disproportionate frequency on the top of a stack of items such that the selected images are the most common images viewable through a transparent product packaging. In certain implementations, empirical sales data is used to determine weighting factors used in the biasing protocol. In still other implementations, a more specific ordering protocol is imposed by a user such that some or all of the sequence of items in a stack or collection is arbitrarily imposed.
