Patent number: 8876468Abstract: A fan system comprises a hub, a plurality of fan blades, a drive system, and a stationary tube. The hub is configured to rotate. The fan blades are mounted to the hub. The drive system comprises a rotatable hollow output shaft. The hollow output shaft is in communication with the hub, such that the drive system is operable to rotate the hub via the hollow output shaft. The stationary tube is inserted through the hollow output shaft. The stationary tube is configured to remain stationary as the hollow output shaft rotates. Wires and the like may be passed through the stationary tube, to reach an accessory mounted at the bottom of the stationary tube. The fan system may also include a detector, such as a heat detector, a smoke detector, or an accelerometer. The detector may power down the fan system in response to detecting certain conditions.Type: GrantFiled: March 15, 2012Date of Patent: November 4, 2014Assignee: Delta T CorporationInventors: Richard M.

Publication number: 20140144018Abstract: A connector apparatus position assurance device ensures that a male connector assembly and a female connector assembly of an in-line sealed electrical connector apparatus of the present invention remain engaged. The connector apparatus position assurance device has contiguous parts that engage various parts of a retention clip of the male connector assembly at different levels of insertion of the connector apparatus position assurance device into the male connector assembly. The insertion of the connector apparatus position assurance device is also accomplished at various stages (i.e., from pre-lock position to final lock position) depending on the insertion level of the female connector assembly into the male connector assembly. Consequently, the effect of the level of insertion of the female connector assembly ensures that the male and female connector assemblies remain engaged.Type: ApplicationFiled: January 29, 2014Publication date: May 29, 2014Applicant: J.S.T.

Patent number: 8721305Abstract: A fan comprises a hub, fan blades, and inserts. The hub comprises outwardly extending mounting tabs that lie along a common horizontal plane. The fan blades are hollow, such that each mounting tab is inserted in the hollow interior of a corresponding fan blade. Each insert is positioned in the hollow interior of each fan blade, between each mounting tab of the hub and the interior surface of the corresponding fan blade. Each insert is configured to position and maintain the chord line of each corresponding fan blade at an oblique angle relative to the horizontal plane of the hub. A kit may include several insert sets to choose from to provide adjustable angle of attack. A fan control system includes a dimmer switch and a control module, which allows the dimmer switch to be used to infinitely adjust the speed of a fan motor within a range.Type: GrantFiled: May 4, 2010Date of Patent: May 13, 2014Assignee: Delta T CorporationInventors: Richard A.

Patent number: 8672649Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.Type: GrantFiled: March 6, 2009Date of Patent: March 18, 2014Assignees: Delta T Corporation, Moog Inc.Inventors: J.

Patent number: 8676510Abstract: A pattern matching unit performs pattern matching on present data obtained this time in clinical examination of a part of a subject and previous data obtained last time in the clinical examination of the part with reference patterns. Reference patterns that are most closely approximate to the present data and the previous data are selected. A distance calculator calculates a distance between selected reference patterns. A determining unit determines whether a re-examination is necessary based on the distance.Type: GrantFiled: July 16, 2004Date of Patent: March 18, 2014Assignees: A&T Corporation, Kochi UniversityInventors: Tatsuhisa Watanabe, Hiromi Kataoka, Akira Horimoto

Publication number: 20140072431Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. Each of the fan blades includes a substantially rigid spine member, a resilient leading edge member, and a resilient trailing edge member. The leading edge member and trailing edge members are removably coupled with the spine member, such that different leading edge members and different trailing edge members may be chosen to customize the leading and trailing edges of the fan blades. Each fan blade may have more than one type of leading edge member or more than one type of trailing edge member. The leading edge member and trailing edge member may each be coupled with the spine member by urging the leading edge member and trailing edge member in a direction that is substantially perpendicular to the longitudinal axis defined by the spine member.Type: ApplicationFiled: September 9, 2013Publication date: March 13, 2014Applicant: DELTA T CORPORATIONInventors: J.

Publication number: 20140011089Abstract: The invention addresses the problem of providing a polyimide precursor, a polyimide precursor solution, and a mixture slurry, each capable of more firmly binding active material particles to a current collecting body. The polyimide precursor solution according to the invention contains a tetracarboxylic acid ester compound, a diamine compound having an anionic group, and a solvent. The solvent dissolves the tetracarboxylic acid ester compound and the diamine compound. As the tetracarboxylic acid ester compound, a 3,3?,4,4?-benzophenonetetracarboxylic acid diester is particularly preferred. Examples of the “diamine compound having an anionic group” include 3,4-diaminobenzoic acid, 3,5-diaminobenzoic acid, and m-phenylenediamine-4-sulfonic acid. Further, the mixture slurry according to the invention contains active material particles in the polyimide precursor solution.Type: ApplicationFiled: March 26, 2012Publication date: January 9, 2014Applicants: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, I.S.T.
