Abstract: A moving element having secondary keyboard for a portable electronic device is placed between a first member and a second member of the device for providing different keyboard sets to improve readability of text when in different operating configurations. When the second member slides out laterally relative to the first member, the moving element remains stayed in the first member, not moving with the second member. When the second member slides out vertically relative to the first member, the moving element slides with the second member along the sliding groove on the first member, and the moving element is exposed on top of the second member to present a concise dialing keyboard. The secondary keyboard contacts corresponding buttons of a primary keyboard directly. Thus, there is no need to provide additional circuit module exclusively for the secondary keyboard such that the cost and volume can be reduced.

Abstract: The present invention is an elastic sweatband including a fabric surface, a peak portion and a trough portion, wherein the peak portion and the trough portion are formed in a longitudinal direction of the fabric surface. The peak portion and the trough portion are paralleled and connected to each other. The peak portion and the trough portion are across two ends perpendicular to the longitudinal direction of the fabric surface respectively. When a force is exerted on the elastic sweatband, a partial of vertical height of the peak portion will be converted into the extension length in the longitudinal direction, so as to provide the extension length in the longitudinal direction of the elastic sweatband.

Abstract: An efficient method for calculating the step-sizes for a frequency-domain equalizer of a discrete-multitone communications system using signal power estimation and tone grouping (SPE-TG) while on-line. The SPE-TG method is used to calculate a plurality of subchannel step-sizes which are then stored in a lookup table. When on-line, the method uses signal power estimation to select step sizes for each tone, and uses these step sizes for frequency domain equalization. The SPE-TG method simplifies the calculations necessary for frequency domain equalization, thereby saving significant hardware and/or processing resources. The SPE-TG method is reliable and robust, and does not depend upon assumptions about the line, location, or channel.

The light source device includes a bent lamp with bent parts for generating the light beam and compensating for the brightness at two ends of the bent lamp; and a set of obscuring units fixed at the two bent parts to partially obscure the light of the lamp.

Thereupon, any surplus material from the stitched cut-out pieces can be cut away, only leaving the very minimum of connecting gathered edges. Then, heating art is implemented to externally apply and cover the joined areas of the gathered edges with hold-down strips containing thermosol or thermal polyurethane (TPU) membrane, thereby fabricating a hat.
