Abstract: This disclosure relates to an engineered a novel synthetic artificial stem cell (SASC) system which mimics the paracrine effect of the stem cell secretome and provides tailorability of the composition for targeted tissue regeneration. This novel SASC system demonstrates the feasibility of developing a completely synthetic, tailorable stem cell secretome which reinforces the possibility of developing a new therapeutic strategy that provides better control over targeted tissue engineering applications. Disclosed herein are biodegradable polymeric microspheres that have been used to encapsulate secretome active agents. These microspheres mimic or have the potential to result in a greater therapeutic paracrine effect compared to stem cells, without the added risk of immunological response or the extra pro-inflammatory, antagonistic or inert factors/cytokines. The compositions may be personalized to any disease and/or individual, therefore, adding a much needed element to therapeutics.

Abstract: An image sensor may include an array of image pixels that is coupled to column readout circuitry, which may read out charge generated by the image pixels. The column readout circuitry may include a column amplifier having analog memory cells. The analog memory cells may include a high gain capacitor and a low gain capacitor coupled in parallel between a column of the image pixels and an input of the column amplifier. A feedback capacitor may be coupled between the input and an output of the column amplifier. High and low gain select switches respectively coupled to the high and low gain capacitors may allow for the output of high and low gain reset values and image signals, which may be used in correlated double sampling operations and which may increase the dynamic range of the image sensor.

Abstract: Embodiments include apparatuses, methods, and systems for jitter equalization and phase error detection. In embodiments, a communication circuit may include a data path to pass a data signal and a clock path to pass a clock signal. A jitter equalizer may be coupled with the data path and/or clock path to provide a programmable delay to the data signal and/or clock signal, respectively. The delay may be determined by a training process in which a supply voltage may be modulated by a modulation frequency. The delay may be dependent on a value of the supply voltage, such as a voltage level and/or jitter frequency component of the supply voltage. A phase error detector is also described that may be used with the communication circuit and/or other embodiments.

Abstract: Embodiments described herein relate generally to monitoring a dining session using smart smallwares. A smart smallware may sense usage or non-usage associated with a dining session of a customer. Based on the sensed non-usage of the smart smallware, the smart smallware may detect a period of inactivity. In response to the detected period of inactivity, the smart smallware may transmit an indication of the detected period of inactivity. This transmitted indication may cause an external monitoring device to notify a waitperson that a customer associated with that smart smallware may require attention. Other embodiments may be described and/or claimed.

Abstract: The present invention relates to a pill box for splitting pills into halves. The pill box comprises a cover and a base which are connected pivotally by a staff. The cover has a blade holder inside, which has a plug pin at the bottom. At the bottom of the cover, there is a partition with an opening. The base has a pill receptacle and a slot. When the blade holder moves down, the blade and the plug pin pass through the opening. The blade cuts at the position of the pill receptacle and the plug pin plugs into the slot. The cover and the base are locked together. When the blade holder moves up and the plug pin completely moves out from the slot, the cover or the base can rotate out with the staff as a pivot. The present invention is safe, reliable, small and portable.

Abstract: A circuit stage such as an input stage is provided for a radio frequency tuner having an input which typically receives a broadband signal comprising many channels. The input stage comprises a low noise amplifier in the form of a long tail pair of transistors and a controllable tail current source. A level detector detects the signal level at the input of the amplifier and controls the tail current source so as to increase the tail current as the signal amplitude rises above a threshold level and so as to keep the tail current fixed when the signal amplitude is below the threshold.
