Abstract:
A device for non-invasive measurement of blood pressure includes a blood pressure cuff, a plethysmographic electrode for acquiring an impedance plethysmogram distal to the cuff and a processing device to inflate and deflate the cuff, generate the impedance plethysmogram and to determine the systolic and diastolic blood pressures. It is determined when the cuff is completely occluding the extremity, e.g., by detecting pulses at a second, partially occluded cuff or by a photoplethysmogram attached to the big toe. The device can be used to measure systolic or diastolic blood pressure or both. It can also be used to take ankle-brachial measurements. An autocorrelation technique can be used to correct noise.
Abstract:
In a system and method for peripheral impedance plethysmography, an electrode for application to the patient's limb includes two outer current electrodes and two inner voltage electrodes. A distance between the two inner electrodes is automatically input into an analyzing device, either as a pre-stored value or as determined automatically from the electrode. Peripheral blood flow is calculated in accordance with that distance.
Abstract:
This device uses electrical impedance and signal processing to measure the small change in volume (“Pulse Volume”) of a limb-segment that occurs with each heartbeat. “Pulsatile Flow” is defined as the pulse volume multiplied by the heart rate and is an index of tissue perfusion. This information can be combined with measured blood oxygen saturation to determine how much oxygen is reaching the tissues. The combination of knowing oxygen saturation and tissue perfusion is far more useful than knowing just one or the other of these parameters.

Abstract:
A new and distinct cultivar of Buxus plant named ‘WINTER JADE’ is disclosed, characterized by an upright plant habit with dense branching and dense foliage cover. Plants have shown resistance to the normal diseases and pests of Boxwood. Foliage is dark lush green. Plants have been observed to tolerate temperatures between 0 degrees F. to 110 degrees F. without negative effects. The dark green foliage color is maintained in both winter and summer under both low and high temperatures. The new cultivar is a Buxus, suitable for ornamental garden purposes.
Abstract:
A system for remediation of a fluid is provided. The system has an inlet configured to supply the fluid to a remediation channel, an injection port in fluid communication with the remediation channel, the injection port configured to inject at least one substance into the liquid, at least on air actuator in fluid communication with the remediation channel downstream from the injection port, the air actuator configured to generate a cavitation pocket, a vortex plate disposed within the remediation channel, and configured to create a swirl in the fluid and further increase the number of cavitation pockets within the liquid. A method of remediating a fluid is also provided herein.
Abstract:
A payment processing system for mobile point-of-sale transactions from a mobile point of sale terminal including a payment card reader having a card interface configured to read data from a payment card, the payment processing system includes an automated support system for proactively generating and presenting support messages for merchants using a mobile point-of-sale terminal. The automated support system generates the support message using a current account context for the merchant account and a plurality of rules that indicate a problem with the merchant account. The automated support system is further configured to generate a plurality of rules for detecting merchant account problems using a knowledge database of support tickets that include a human generated response to a merchant account problem and a corresponding merchant account context at the time of the human generated response.
Abstract:
Methods for determining the hardness and/or ductility of a material by compression of the material are provided as a first aspect of the invention. Typically, compression is performed on multiple sides of a geologic material sample in a contemporaneous manner. Devices and systems for performing such methods also are provided. These methods, devices, and systems can be combined with additional methods, devices, and systems of the invention that provide for the analysis of compounds contained in such samples, which can indicate the presence of valuable materials, such as petroleum-associated hydrocarbons. Alternatively, these additional methods, devices, and systems can also stand independently of the methods, devices, and systems for analyzing ductility and/or hardness of materials.
Abstract:
A portable table system includes an article of luggage that has a handle and the handle has a pair of uprights. A table is removably coupled to the handle such that the table may support an object. The table is collapsible such that the table is stored in the luggage. A pair of supports is provided and each of the supports is coupled to the table. Each of the supports is removably coupled to the handle such that the table is retained in a horizontal orientation.
Abstract:
Methods and systems facilitate facilitating notifying a user of potential savings associated with a parts order. According to various implementations, an order file containing order information associated with a first part is received. A determination is made, based on inventory information, that the first part is available from each of a first and second part sellers. Based on a price matrix, a potential cost savings is determined associated with ordering the first part from the first part seller rather than the second part seller, and a savings beacon associated with the part, and indicating the potential savings, is generated and provided to the user.
