Abstract: A sock for covering at least a foot of a human wearer includes: a knitted toes-covering fabric-region, configured to cover toes of the foot; a knitted sole-covering fabric-region, configured to cover a sole of the foot; and a knitted toes-region stabilizing component, located between the knitted toes-covering fabric-region and the knitted sole-covering fabric-region. The knitted toes-region stabilizing component is configured to stabilize, and to prevent shifting or slippage of, the knitted toes-covering fabric-region in response to body movements. The knitted toes-region stabilizing component is a knitted band that is formed of a first yarn which is a High-Friction Low-Slippage yarn; the knitted toes-covering fabric-region and the knitted sole-covering fabric-region are knitted of a second, different, yarn.

Abstract: A ring resonator based T-shaped duplexer for use in communication systems, the T-shaped duplexer comprising a T-shaped microstrip duplexer body having a first rectangular-shaped body section and a second rectangular-shaped body section that extends from the first-rectangular shaped section in a perpendicular position relative to the first rectangular-shaped section, three connection ports including a first connection port disposed at an open end of the second rectangular-shaped body section, a second connection port disposed at one end of the first rectangular-shaped body section, and a third connection port disposed at another end of the first rectangular-shaped body section, and two bandpass filters, each bandpass filter comprising a ring resonator structure having a circular shape, an outer edge of the ring resonator structure being connected to the first rectangular-shaped body section of the T-shaped microstrip duplexer body, wherein each of the two bandpass filters creates an Electromagnetically Induced

Abstract: A sock includes: an elongated toe-area to cover at least all phalanges of all toes of a foot of a wearer of the sock; a sole area to cover a sole of the foot; and an ankle area to at least partially cover an ankle of the foot. The elongated toe-area is distinct from other areas of the sock. The elongated toe-area extends backwardly towards the ankle, covering part of the sole of the foot; optionally covering between 25 to 50 percent of the length of the foot. Optionally, the toe-area is a split toe-area having two or more sub-regions. Optionally, the elongated toe-area is a non-symmetrical trapezoid elongated toe-area.
