Abstract: A battery comprises a housing, one or more energy cells contained within the housing, and a battery monitoring system contained within the housing. The battery monitoring system includes a health sensor configured to take health measurements corresponding to a health condition of the battery. The battery monitoring system includes an electronic module configured to communicate one or more signals corresponding to the health measurements such that the health condition may be determined.

Abstract: A new power and area efficient ADC-digital co-design approach is introduced to IF digital beam forming that combines continuous-time band-pass ?? modulators and bit-stream processing. An array of compact (0.03 mm2), low-power (13.1 mW) delta sigma modulators directly digitizes 260 MHz IF signals from eight input elements. Digital beam forming is directly performed on the over-sampled, undecimated low-resolution outputs of the delta sigma modulator array. The unique combination of delta sigma modulators and bit stream processing has several advantages.

Abstract: An invalid hoist comprises a lifting arm, a sling hanger support angularly displaceable relative to the lifting arm about a vertical or substantially vertical axis and a sling hanger which is of unitary construction pivotable about a horizontal axis relative to the sling hanger support and which presents two spaced sling attachment points on one side of the horizontal axis and at least one sling attachment point on the other side of the horizontal axis. A rotary drive mechanism is provided for pivoting the sling hanger about said horizontal axis relative to the sling hanger support and switch means are provided for selectively rotating the rotary drive means in one or other of two opposite directions. The sling hanger support is of generally inverted U-shape configuration having a cross member and two parallel or substantially parallel limbs depending from the cross member.
