On March 17, Advanced Technologies developed a patent related to laser surgery techniques. They spent $1,300,000 to develop the patent internally, consisting of personnel ($850,000), equipment ($330,000), and materials ($120,000). The company also had the following additional costs: $30,000 in legal fees associated with the purchase and filing of the patent, $45,000 to advertise its new laser surgery techniques, and $55,000 to train employees. What is the recorded cost of the patent? Total capitalized cost

00:01 Okay, so in this problem we're talking about laser surgery, and we know that 10 to the minus.

00:07 Short pulses are better than long pulses, so we want number of the, of certain photons in one pulse and the average power during a certain number of pulses.

00:19 So let's get down the givens.

00:22 So short pulse, so let's do call time equals 10 to the minus 12 seconds, and then next we get the power.

00:40 I think it was 10 to the 12 watts and 65 pulses so let's see and equals 65 and then let's say it called a time in between them delta t so 200 times 10 to the minus 6 seconds so 200 microseconds and that was better than longer pulses so we want the number of i'll call that nph equals question mark and then we have the wavelength is 10 .6 times 10 to the minus 6 microns or not micron meters 10 .6 microns though.

01:56 So we want that and then the average power.

02:04 Ooh, this is a little confusing.

02:06 We went the average power during 65 pulses delivered in 200 microseconds.

02:10 But then it's saying, oh, i see, yes, there is 65 pulses in 200 microseconds.

02:17 Okay.

02:17 So i thought it was saying every 200 seconds you pulse.

02:20 But that makes a problem a bit easier the way that they wrote it.

02:25 So we want some average power.

02:29 P equals question mark p average.

02:37 So let's see, number of photons.

02:41 Well, we know that a single photon is going to have an energy of h -c divided by lambda, and so we have all of that information.

02:57 So then the number of photons is going to be the ratio of the total energy to the energy per photon.

03:07 So i'll call that e -p -h for energy per photon.

03:12 So now we just need how much total energy is delivered.

03:17 And so we know that each pulse, it's 10 to the 12.

03:25 Each pulse is 10 to the 12, and then there's 65 of them.

03:30 And then each one of them takes this amount of time.

03:33 So powers energy over time, so we can get the total energy per pulse.

03:38 And then e -total is going to be the number of pulses times the energy per pulse.

03:45 And i really don't want to create another variable here.

03:48 Let's just say we want to look for the energy per pulse, and then that's just going to be the power times the time, right? powers energy over time...
