Abstract: The present invention relates generally to a geospatial database access and query method, and more particularly to a map and Inertial Measurement Unit/Global Positioning System (IMU/GPS) navigation process. With the location information provided by an IMU/GPS integrated system, the geospatial database operations, such as database access and query, are sped up. With the map data from a geospatial database, the navigation performance and accuracy are enhanced. The present invention also supports real time mapping by using IMU/GPS integrated system as the positioning sensor.

Abstract: A roll core is adapted for fitting into an open end of a roll core for supporting said roll core while said roll core is capable of rotating with respect to said handle. The handle includes a hollow holder body having a plurality of side-by-side side wall arcuate segments and a plurality of stiffening ribs formed longitudinally around the holder body, wherein the stiffening ribs are positioned spacedly apart to separate the plurality of arcuate segments into groups of resilient rotor supports adapted for compressive constraint within said roll core for enabling the roll core to be smoothly rotated with respect to the holder body. The handle further includes a flange radially and outwardly extended from a proximal end of the holder body integrally.

Abstract: A plunger anti-detachment mechanism incorporates with a syringe which includes a hollow barrel, a hollow needle held at one end of the hollow barrel, and a plunger adapted to coaxially travel through the barrel. The plunger anti-detachment mechanism includes at least a locking stopper radially extended on the barrel and at least a resilient arm, having a locking latch outwardly extended therefrom, radially extended from the plunger wherein the resilient arm is adapted to move from an unlocked position to a locked position. At the unlocked position, the locking latch is moved away from the locking stopper such that the plunger is capable of freely traveling through the barrel, and that at the locked position, the locking latch is extended to the locking stopper so as to block up an axial movement of the plunger with respect to the barrel and interlock the plunger with the barrel.

Abstract: A holding arrangement, which is incorporated with a carrying container, includes a handle seat securely mounted on a top side of a container body. The handle seat has receiving chamber indented thereon to form a first and second longitudinal opposed inner walls and an arch wall integrally extended from the first inner wall to form a holding cavity to communicate with the receiving chamber. The receiving chamber is arranged to receive the gripping handle therein while a side biasing wall of the gripping handle faces towards the arch wall. Therefore, when the bottom portion of the holding object is disposed in the holding cavity, the circumferential surface of the holding object is biased by the arch wall and the side biasing wall of the gripping handle so as to securely hold the holding object on the upper side of the container body.

Abstract: An angular rate amplifier, which is adapted to amplify useful signals, which are proportional to rotation motion of a carrier, and to suppress noise, which is not proportional to rotation motion of a carrier, in output signals from an angular rate producer, including a MEMS (MicroElectronicMechanicalSystem) angular rate sensor. Compared with a conventional amplifiers, a noise shield and a co-resident trans impedance amplifier are utilized to achieve high signal/noise ratio. Furthermore, the angular rate producer and the noise shield and a co-resident trans impedance amplifier are used in a micro inertial measurement unit (IMU) to improve performance of the micro inertial measurement unit to form highly accurate, digital angular increments, velocity increments, position, velocity, attitude, and heading measurements of a carrier under dynamic environments.
