  • Patent number: 11987817
    Abstract: Disclosed is a process of manufacturing cell spheroids using a bioink. More particularly, provided is a method of manufacturing a cell spheroid, the method including extruding a first bioink including an alginate; extruding a second bioink including cells into the extruded first bioink; adding a calcium chloride (CaCl2) solution to the alginate included in the first bioink; and dissolving the second bioink, present in the first bioink, in a cell culture medium to form a cell spheroid from the cells.

  • Publication number: 20130215745
    Abstract: Dynamic buffer management for wireless communication systems facilitates enhanced throughput. The dynamic buffer management reduces buffer allocation for the current service period near the end of the current service period, and allocates the freed buffer space to one or more subsequent service periods before they begin. As a result, the host may begin to transfer data for those subsequent service periods in advance, so that data is immediately available to send when the subsequent service periods begin.

  • Patent number: 8024145
    Abstract: Aspects of a method and system for signal generation via a temperature sensing crystal integrated circuit are provided. In this regard, a temperature sensing crystal integrated circuit (TSCIC) comprising a memory and a crystal or crystal oscillator may generate a signal indicative of a measured temperature. The generated signal and data stored in the memory may be utilized to configure one or more circuits communicatively coupled to the TSCIC. The data stored in the memory may characterize behavior of the TSCIC as a function of temperature and/or time. The data characterizing the behavior of the TSCIC may indicate variations in frequency of the crystal or crystal oscillator as a function of temperature and/or time. The data characterizing the behavior of the TSCIC may comprise one or both of a frequency value and a frequency correction value.

  • Patent number: 7558160
    Abstract: A method for demodulating a focusing error signal in an optical disc system, comprising the steps of (A) generating a beam strength signal and the focusing error signal, (B) sampling the beam strength signal and the focusing error signal at an appropriate sampling rate, (C) removing a static offset from the beam strength signal and the focusing error signal, (D) calibrating a peak-to-peak value of the beam strength signal and the focusing error signal, and (E) determining an appropriate phase to (i) demodulate the focusing error signal and (ii) calculate a vertical position of a lens in relation to a disc.
