Home Automation Lightning Motion Sensor and Zigbee Wireless Essay

Home Automation Lightning Motion Sensor and Zigbee Wireless - Essay Example Most presence detectors have an inbuilt light sensor (lux) that will turn off the lights if there is sufficient natural light. Regulating lights with a presence detector may save up to 65% of the total cost spent on lighting energy (CP Electronics, 2013). How the system works Presence detectors also known as PIR (Passive Infra-Red) work on a principle similar to that applied in motion detectors. These devices log the thermal radiations of their environments or area under detection. When thermal radiation in the area is detected, for example, in the case of a person coming close to the sensor, the detector will convert these vibrations into measurable electrical signals which will then turn on the lights. Presence detectors utilised in controlling lighting assist in the continuous adjustment of the output of faint lighting systems. This functionality facilitates management of energy saves costs over the conventional switching systems. Presence detectors provide an automatic hands-off lighting system that combines user comfort with an optimum energy consumption (Theben, 2011). Belkin's new device called WeMo makes home automation simpler. According to the company manufacturers, the device allows the user to control home-entertainment and other applications using iOS devices. Belkin's WeMo system incorporates a number of devices that are linked to the users Wi-Fi network. The system can then be managed by an iPad app or WeMo iPhone. Unlike other home automation systems, WeMo is entirely modular, and the user can add more nodes to increase its effectiveness (Linked in, 2013). How WeMo works The WeMo Switch and WeMo Motion are the present WeMo devices that exist today. The WeMo Switch is plugged into a wall outlet and serves as a remote-controlled socket that turns connected devices on or off according to the user’s command. The WeMo Motion device is also plugged into a wall socket, and has a 6-foot power cord which links to a motion sensor. Both the WeMo Mot ion and WeMo Switch are linked to the wireless network of the user, and the WeMo iOS app detects these components automatically. Various home appliances can be connected by plugging them into the WeMo Switch. The appliances connected to the WeMo Switch can then be turned on or off using iOS app available in the system. Therefore, the WeMo Switch allows the user to check if certain household appliances have been turned off in order to avoid the requirement of running an entire home check. The WeMo Switches have power buttons that replace the switch on the wall socket. WeMo Switch Setup The WeMo is not available officially, but its setup is a breeze. Once turned on, the isolated WeMo device creates a wireless network named as WeMo-XXX, where XXX is the device’s ID number. The next step involves connecting the iPad or iPhone to the network, and a free WeMo app is initiated. The WeMo app will then detect the primary Wi-Fi network and pull the required data configuration automatic ally. The WeMo app will also ask for a Wi-Fi password to ensure the user’s network is secured. The device collects additional configuration information necessary for its operations and then links to the wireless network. In addition to the ability to remotely switch domestic devices on and off, the principal selling point of the WeMo system is its simplicity of deployment. The WeMo Switch will also come at an affordable cost of about $50, according to the company reports (Honeywell, 2013).

Postoperative pain management Essay Example | Topics and Well Written Essays - 3000 words

Postoperative pain management - Essay Example Management of pain following a surgery employs oral or rectal analgesics, intramuscular opioid injections, systemic opioid analgesia, continuous subcutaneous infusion of analgesics, and patient-controlled analgesia (PCA).Management of pain following a surgical procedure is one of the major challenges and source of concern for health care providers (Berge et al, 2004). However, surveys have revealed that hospital postoperative pain management, such as opioid intramuscular injections are frequently inefficient, resulting in unrelieved pain in approximately 50% of patients (Steinberg et al, 2002). Various studies have shown that postoperative pain has significant influence on the recovery of the patient, length of stay in the hospital, mobility, cost of hospitalization and also postoperative morbidity like cognitive dysfunction and pulmonary complications (Pain Management Guideline Panel., 1992). According to Sommer et al (2008), moderate to severe pain occurs in more than 50 percent of patients who undergo abdominal surgery It is crucial to control postoperative pain and currently in every hospital in the western world, control of post operative pain is given utmost importance. An understanding of pain management in the postoperative period can be enhanced through reflection. Reflection is evaluation and examination of thoughts and actions of oneself. For health practitioners, reflection means focusing on the interaction of oneself with colleagues and environment in a particular situation so that they are able to evaluate their own behavior. â€Å"Reflection gives scope for better understanding of oneself so that existing strengths can be used to build-up for future actions "(Somerville and Keeling, 2004). In order to be an effective practitioner, one must be able to identify one's strengths in approaching a problem, assess one's level of competency and improve on what one thinks are the weaknesses so that when the same problems arise in the future, the right ap proach can be adapted. Reflection is also an opportunity for professional growth and development to increase competence in the nursing practice (Alexander, Fawcett and Runciman, 2006). Reflective practice is very essential for nursing clinical practice because it helps the nurse to understand, assess and learn through the experiences during clinical practice (Burns and Grove, 2005). In the following assignment, I shall discuss about management of a patient with postoperative pain based on Gibbs (1988) Reflective Cycle. This is because, Gibbs Reflective Cycle is a straight forward and recognized framework for reflection wherein it enables clear description of the situation of the patient, the analysis of feelings, evaluation of the experience, analysis to make sense of the experience, conclusion where other points are considered and reflection upon experience to examine what you would do if situation arose again. Case description Mr. X was a 67 years old male patient, who I looked af ter in a Surgical High Dependency Unit (SHDU). He was transferred from theatre following Whipples, where a total pancreatectomy was performed along with the removal of Gall Bladder and Duodenum.  Past medical history included hypertension and chemotherapy 2 years ago following the diagnosis of pancreatic cancer. He was also underweight. The patient was transferred to SHDU in a stable condition. On the 1st day post op, the Epidural Analgesia’s catheter was dislodged by accident and according to the protocol (NHS 2009), it could not be used anymore. Although, the patient had prescribed oral pain reliefs as required, Mr. X showed discomfort and pain, once resting and moving in bed. Because of the risk of post operative complications including pressure sores and chest infection, the issue was highlighted to Pain Management Nurse, who prescribed Patient Controlled Analgesia (PCA). The Pain Management Nurse provided short educational session for Mr. X, as he never used PCA before and appeared to be anxious about
