  • Patent number: 9257927
    Abstract: An apparatus and method is provided for controlling a stepping motor in a digital photographing apparatus, the apparatus including: a temperature measuring unit for measuring a temperature; and a digital signal processor (DSP) for determining a measured temperature driving value of the stepping motor in correspondence with the measured temperature, changing the determined driving value based on a target position to which the stepping motor is supposed to move, and outputting the changed driving value to the stepping motor. Accordingly, power consumption of image capturing apparatuses may be eventually reduced by reducing power consumption of a stepping motor by driving the stepping motor with different driving values depending on temperatures and positions thereof.

  • Patent number: 9219206
    Abstract: Provided are a package including a first conductive layer on a patterned layer, an insulating layer on the patterned layer burying the first conductive layer, a second conductive layer on an outer surface of the insulating layer, and a third conductive layer in the insulating layer electrically connecting the first conductive layer with the second conductive layer. A substrate is formed by printing or coating a paste- or ink-type insulator and conductor on a patterned layer formed on a sapphire wafer. No void is created between the substrate and LED chip, thus enhancing attachment strength. The ceramic-containing insulator is cured at a low temperature, thereby minimizing contraction of and damage to the wafer when the ceramic is fired. Printing methods utilizing viscous paste or ink solves problems with co-planarity of substrate that occur in existing wafer-to-wafer bonding processes and renders several steps of the existing substrate manufacturing process unnecessary.

  • Publication number: 20150324539
    Abstract: An improved emergency response system is provided. The system includes a patient or subscriber location database having a schedule of patient or subscriber activities. In one implementation, an emergency services server detects when the patient or subscriber is having a possible medical event as indicated by medical physiologic data transmitted from a wireless communication device proximate the patient. A third party such as a technologist and/or doctor diagnoses the patient and determines whether treatment is required. If treatment is required, a phone located remotely from the patient is used to call an emergency services first responder from a public safety access point in the patient's location. The remotely located phone has an automatic location identification database record that is updated based on the patient's current location as indicate by the patient location database.
