Title: Blower and heat exchanger using the same
Inventor: IWASAKI TAKAHIRO
IPC: F01P11/20
Filed: 2004-09-17
Abstract: A freeze-lock phenomenon where water drops in a gap between a blade wheel (1a) and a shroud (1c) freeze to cause the blade wheel (1) not to rotate is prevented from occurring. A water discharge opening (1m) is provided over a range of about 20 degrees to one side from the lower end side of a ring section (1h) of the shroud (1). This makes it possible that, even if water drops that adhere on the surface of the blade wheel (1a) and the shroud (1c) (the ring section, particularly) gather on the lower side by gravity, the water can be quickly discharged. As a consequence, water drops are prevented from pooling in the gap between the blade wheel (1a) and the ring section (1h)(shroud (1c)). This prevents a freeze-lock phenomenon in time where temperature is low, or in wintertime.

Title: Object Detection Using Feature Responses
Inventor: KIRSCH GRAHAM
IPC: G06V10/147
Filed: 2009-06-16
Abstract: Objects of a class, such as faces, are detected in an image sensor. The sensor includes a detector with a buffer which stores data in raster order. The detector reads the data out in Z order (fig. 3) to perform object detection by computing small scale feature responses using the Z-ordered image data and determine whether any objects of the object class are present based on the feature responses. The detector can downscale the image data concurrently as the object detection is performed and use the downscaled image data to continue the detection process. The image data can perform detection even if the image is rotated. Coefficients are selected dependent upon the chosen orientation to use for detection, these coefficients are then used to determine the presence of objects in the selected orientation are present. Alternatively, coefficients match a location of the image. Also disclosed is a first and second coefficient memory which are addressed by logic to concurrently provide first and second coefficients using first and second address vectors.
