Appl. No.:

6/775625

Inventors:

Craig E. Nelson - Seattle WA

Assignee:

TAB Leasing - Seattle WA

International Classification:

G01H 310

US Classification:

73 1R

Abstract:

Apparatus for measuring the power of radiation that includes float means (16) and force balancing means (48, 50, 60, 80). The float means includes a target (46) for the radiation and is constructed such that the net gravitational force, including buoyancy force, if any, acting on the float means tends to accelerate the float means in a first direction. The force balancing means includes drive means (80) for providing a drive signal and means (50) responsive to the drive signal for exerting a balancing force on the float means in a second direction opposite the first direction, such that the magnitude of the balancing force corresponds to a characteristic of the drive signal. The drive means is adapted to vary such characteristic of the drive signal, to thereby vary the balancing force, such that when the drive signal is controlled so as to cause the float means to be suspended at a predetermined height, the characteristic of the drive signal provides a measure of the force exerted on a target as a result of the radiation striking the target, and therefore of the power of the radiation. The float means preferably comprises a magnetic material (48) and the force balancing means comprises an electromagnet (50). The apparatus may directly measures the force of acoustical or electromagnetic radiation on the target, or may measure the change in buoyancy of the target caused by electromagnetic radiation heating and changing the density of the target.

Appl. No.:

6/650806

Inventors:

Craig E. Nelson - Seattle WA

Assignee:

TAB Leasing - Seattle WA

International Classification:

G01N 2900

US Classification:

73632

Abstract:

A precision acoustic source that is capable of producing acoustic radiation having peak and average power levels that are independently and simultaneously adjustable. The apparatus comprises an acoustic transducer and drive means for producing a drive signal comprising a series of drive pulses to the transducer, such that the transducer produces acoustic radiation having selected peak and average power levels. The drive means comprises means for establishing a series of fixed-length clock cycles, means for generating a series of trigger signals, pulse generating means responsive to each trigger signal to produce a selected number of standard pulses, an amplifier for generating a drive pulse in response to each standard pulse. The amplifier adjusts the amplitude of each drive pulse such that the peak power of the acoustic radiation is equal to the selected peak power level. Each trigger signal occurs either R or S clock cycles after the preceding trigger signal, R and S being positive integers.

International Classification:

G01H 2500

US Classification:

73 1B

Abstract:

An apparatus for calibrating a force measuring instrument of the type that includes a force sensitive element submerged in a liquid. The apparatus comprises a magnetic object having a known weight when submerged in the liquid, and an electromagnet. The electromagnet includes a core having a first end that extends beneath the surface of the liquid to a position near the upper surface of the force sensitive element. The electromagnet further includes a coil surrounding a portion of the core, means for energizing and deenergizing the coil, and a thermal insulator surrounding the first end of the core to prevent the core from contacting the liquid and to limit heat flow from the core into the liquid. When the coil is energized, the magnetic object is picked up from the force sensitive element and adheres to the insulator. When the electromagnet is deenergized, the magnetic object falls back onto the force sensitive element for calibration of the instrument.

International Classification:

H04L 29/06

Abstract:

Methods, systems, and media are shown for creating and deploying honey tokens for intrusion detection in a remote computing resource system. Resource modules provisioned for a tenant are identified for intrusion detection. For each identified resource modules, a provisioned resource having a corresponding access credential is allocated and the access credential is deployed in the identified resource module. A data entry is created in a token mapping store that identifies the access credential and the resource module. Access logs are scanned to detect access attempts. For each access attempt, the token mapping store is searched for a data entry with an access credential that matches the access credential of the access attempt. If found, an alert is generated that includes the identified resource module of the matching data entry.
